Flo Rida

Kate Upton recently got that booty spanked by Flo Rida - on stage, and in jest, of course. Though we're sure the rapper did take some pleasure in it.

At Samsung's Spring 2013 Launch Party this week for some reason, Kate Upton joined Flo Rida in a sexy blue dress. That will liven up a tech convention!

The highlight: As Flo dropped his classic "Low" lyric, "She turned around and gave that big booty a smack," well, that's pretty much what happened up there.

Avert your eyes, Jake Davidson …

Taylor Swift treated her fans to another special guest this week.

During a concert in Miami, the 19-year old sensation brought Flo Rida out on stage and jumped around with him on a version of "Right Round." Watch the fun now:

As she tours across the country, Swift has been asking various artists from her venue's hometown to join her for takes on their most popular hits. Other notable guests have included:

• Shawn Colvin in Austin, Texas.
• Usher in Atlanta, Georgia.
• Justin Bieber in Los Angeles.

No one can ever accuse America's Got Talent of catering to just one demographic.

During the same results show that featured Susan Boyle debuting a song off her new album, Nicki Minaj Flo Rida and David Guetta took to the stage for an energetic rendition of "Where Dem Girls At."

Minaj is coming off an appearance at the MTV Video Music Awards and a duet on "Super Bass" with Taylor Swift. Check out her latest performance now:

Rapper Flo Rida hit a real "Low" point this morning when he was busted for DUI - in the state spelled the same way as his name, only without the space.

Probably not a coincidence. Flo got popped in Miami Beach in a red and black Bugatti - a ride worth $1.7 MILLION - after he was swerving in his lane.

During the traffic stop around 3:30 a.m., the police detected the odor of alcohol, and Flo was given a field sobriety test, which he performed poorly on.

Flo Rida, whose real name is Tramar Dillard, was arrested on suspicion of DUI and taken to a station where he joined our celebrity mug shots gallery.

Sources say Flo's blood alcohol level was more than double the legal limit.

The police report notes that large crowd gathered around Flo after cops pulled him over, and that several bystanders were "trying to get officers to let [Flo Rida] go."

"Some individuals were offering to drive [Flo] home."

Always nice to see an outpouring of support from the community.

Brandy and Flo Rida are definitely close. But are they dating?

Let's ask the sister of Ray J herself. "I've seen the photos of me and Flo Rida," Brandy writes on Vibe.com. "I don't want to say that we're a couple."

But, the singer/actress also goes on to note ... "I can definitely say that he's somebody in my life and I'm definitely interested but I'm not serious with anybody. I'm a little bit afraid to give my heart away right now. It's very scary."

Hmm. She's dropping hints, Flo Rida! You better be worth it!

Another reason the singer's so cautious. Daughter Sy'rai.

Is Flo Rida spinnin' Brandy's head right round?

"My daughter hasn't seen me with anybody in five years," she writes. "I'm very selective when it comes to that because I want to make sure that it's real. I don't want her to see me with just anybody because she means everything to me."

But Brandy and Flo Rida weren't hiding any affection as they cuddled up at her 31st birthday bash in February in South Beach. The rap star cheered her on as she blew candles out and the two were spotted holding hands and getting "snuggly."

They're totally hitting it, who are we kidding.

As for what she wants in a man, Brandy says: "You have to be a strong guy to be in a committed relationship. If you're not ready, then don't tell me you are."

"Be honest with a girl ... Don't tell somebody they're your girlfriend, then you go out and act like you don't have a girlfriend. That's just not right."

Damn straight. You listening, Rida?
