Whitney Houston

Bobby Brown, this may be your prerogative, but it's a really bad idea.

According to sources in the publishing world, the singer was planning to pen a memoir about Whitney Houston a few years ago, but interest "wasn't that great" at the time. Now, however?

"The market has changed," this insider tells The Huffington Post. "Now is the time for a book that details an honest look into the life of Whitney."

But there's no way Brown would exploit Whitney's death, right? Not when daughter Bobbi Kristina is suffering through such a tragic downward spiral, right?

"This is a man who left his ex-wife's funeral because he didn't like his seats and went to a paying gig that night," a friend of Whitney tells the site. "He didn't get on stage that night because he needed to sing his greatest hits or because Whitney would have wanted him to entertain his fans, he did it to get a paycheck - the same reason he now wants to write a tell-all book."

Sadly, that's a very good point.

Mariah Carey is the latest celebrity to speak out on the death of Whitney Houston. But it isn't easy for the artist.

"I'm almost incapable of talking about this still," Mariah said today on Good Morning America. "It's very heavy emotionally."

The two legends collaborated on "When You Believe," a duet featured in the following video and a subject on which Mariah spoke at length in the interview.

"It was great and I don't think people could ever understand our relationship," she said. "There was always this supposed rivalry in the beginning and then we did the duet and we became friends."

Carey attended Whitney's funeral in New Jersey, describing the ceremony as "gorgeous" and concluded her thoughts about Houston with these simple words:

"I loved her. We all loved her. May she rest in peace... her legend's gonna go on forever."

Based on her reaction to her mother's death - a pair of hospitalizations and rumored drug use - it's no surprise that the family of Whitney Houston is concerned over the emotional well-being of Bobbi Kristina Brown.

But a rep for the family now confirms they are worried about her financial well-being, as well.

On Saturday afternoon, The Associated Press provided a live feed of the funeral in Newark, one that was posted by countless websites (including THG). However, we were required to take down the video within 24 hours and this is why:

The family has "agreed to license footage to several media outlets," an insider tells TMZ, adding that the Houstons are charging "customary fees" to ... "help maximize the estate for the benefit of Bobbi Kristina."

The ceremony lasted for a couple hours and included performances by Stevie Wonder (above), Alicia Keys, R. Kelly and a beautiful eulogy by Kevin Costner.

Due to leg spasms and muscle pain, Aretha Franklin was unable to attend Whitney Houston's funeral on Saturday, canceling not only her appearance but a planned performance in honor of her goddaughter, as well.

But the late legend was very much in Franklin's thoughts the evening before, as she played a concert for fans at Radio City Music Hall in New York City and honored Houston with a pair of covers.

“Remember the hits and forget the misses,” Aretha told the crowd. “I’ll always look back and remember her singing..."

And, with that, Franklin broke into a rendition of "I Will Always Love." Watch it and a version of "The Greatest Love of All" now:

According to a new report, the family of Whitney Houston has more reasons than ever to be concerned over the future of Bobbi Kristina Brown.

The 18-year old daughter of Whitney and Bobby Brown has been in the spotlight ever since her mother passed away, with loved ones supposedly so concerned over her spiraling state that they were pushing all week for her to enter rehab - and that was prior to the latest alleged incident.

Following Houston's funeral on Saturday, sources tell The Daily Beast that family members were "freaking out" because they could not locate Bobbi Kristina.

The combination of her mother's passing, and the controversy surrounding her father's early exit from the memorial - Bobby Brown showed up with an entourage, got angry over his seating assignment and departed after just 20 minutes - was just too much for the teenager to handle, according to those on the scene.

She was reportedly found at a hotel "getting high."

Whitney Houston's close friend and The Bodyguard co-star Kevin Costner delivered a touching speech at her funeral yesterday in Newark, New Jersey.

He recalled to mourners gathered at the church and fans watching online that Houston, despite her fame, was a humble woman who doubted herself.

"The greatest pop star in the world didn't think she was good enough," Costner, 57, said of Houston, who died of a possible overdose last week at 48.

"There were a thousand things that seemed to her to be wrong."

Kevin Costner Eulogy For Whitney Houston

Kevin said there were many men who could've played his part in their iconic 1992 film, after which he remained close to Houston, but there was only one Whitney.

When she was screen-testing for the role, which was put in production a year later than slated because she was on tour, Whitney Houston asked herself:

"Am I good enough? Am I pretty enough? Will they like me?"

As those attending the funeral laughed, Costner recalled how she almost sabotaged herself re-touching her own makeup, which melted under the studio lighting.

"I wanted to tell her that the game was rigged, that I didn't care how the test went, that she could fall down and start speaking tongues," he said.

"That no matter what she did, I'd find a way to explain it as an extraordinary acting choice. And gee, weren't we lucky to have her?"

Indeed. R.I.P.

After days spent arguing with Whitney Houston's family over whether or not he'd attend his ex-wife funeral, multiple sources confirm that Bobby Brown continued arguing with his former in-laws today.

And actually left the memorial after just 20 minutes as a result.

Both E! News and TMZ report that Brown brought an entourage of nine people in to the Newark church. It's unclear exactly what happened from there, but the singer was spotted exiting the house of worship shortly after the service began.

"I am at Whitney's funeral. I spoke with Bobby Brown trying to calm him down and not distract from the services. Today is about Whitney!" Al Sharpton Tweeted, while Access Hollywood's Shaun Robinson says a "seating arrangement" dispute was at play.

Brown also has a concert gig tonight in Connecticut with New Edition, but it's believed this disagreement with Whitney's family is the reason why he left the premises so quickly.

UPDATE: Brown has released the following statement:

“My children and I were invited to the funeral of my ex-wife Whitney Houston. We were seated by security and then subsequently asked to move on three separate occasions. I fail to understand why security treated my family this way and continue to ask us and no one else to move. Security then prevented me from attempting to see my daughter Bobbi-Kristina.

"In light of the events, I gave a kiss to the casket of my ex-wife and departed as I refused to create a scene. My children are completely distraught over the events. This was a day to honor Whitney. I doubt Whitney would have wanted this to occur. I will continue to pay my respects to my ex-wife the best way I know how.”

"She would call you for no reason at all, but just to say 'hi.' She was a beautiful human being - really caring, beautiful, thoughtful."

So said Alicia Keys today, holding back tears, prior to breaking into a rendition of "Send Me An Angel" in honor of the late Whitney Houston. Watch for yourself now:

Stevie Wonder also performed at the memorial, while Houston's former co-star in The Bodyguard was applauded for his beautiful tribute to the part-time actress.

"To you, Bobbi Kristina, and to all those young girls who are dreaming that dream, thinking that maybe they aren't good enough, I think Whitney would tell you, guard your bodies," said Kevin Costner. "And guard the precious miracle of your own life. Then sing your hearts out.

"Off you go Whitney, off you go. Escorted by an army of angels to your heavenly Father. When you sing before him, don't you worry. You'll be good enough."

During an emotional Whitney Houston funeral today, which included moving speeches from friends and loved ones, Stevie Wonder took to the piano at one point and shared memories of the late artist.

He praised God for simply allowing him to live at the same time at Houston, talked about recording a duet with her in the studio and then made onlookers laugh by owning up for a mini crush on the legend.

Wonder then went ahead and did what he does best: sing beautifully. Watch and listen to him pay tribute to his friend now:

Stevie Wonder Performs at Whitney Houston Funeral
