Rob Lowe

Rob Lowe tried to teach Bella Thorne a valuable lesson via social media on Thursday.

And the lesson was this:

In the immediate aftermath of terrorists coordinating multiple attacks in Paris on Friday night, killing over 120 people in the process, countless celebrities took to Twitter and sent along their prayers and well wishes.

But not Rob Lowe.

Not every celebrity out there is ready to forgive Ariana Grande.

The singer remains in pretty hot water for having visited a bakery this week and been caught on camera saying she hates America when looking at a tray full of donuts.

As the sports saying goes, Father Time is undefeated. Everybody ages eventually, even Hollywood's rich and famous and attention-seeking reality TV stars.

Not all celebrities are created equal, however. 35 in Hollywood is not the same as 35 in McIntyre, Ga., as the side-by-side photo comparison below illustrates.

We're gonna need a bigger TV...

Are you ready to go back into the water, television and animal lovers?

It's no secret that actors are often booked to play characters of much younger ages. Kerr Smith was 26 when he played 16 year old Jack McPhee on Dawson's Creek.

His incredibly youthful appearance (which has since become a full head of gray hair by 40) worked in his favor. Other celebrities have ridden a similar wave of good fortune. 

If one thing's for sure after looking through this slideshow it's that Joan Rivers' plastic surgeon needs to start handing out his business card on the red carpet. 

Or we could just let people age like they're supposed to so they don't end up looking like Joan Rivers one day. Yeah, there's that option.

Rob Lowe sat down with Oprah recently, and for some reason the topic of Justin Bieber came up. Rob remarked that even Justin's fans don't "give a sh!t about his music," which may sound like an awesome instance of Bieber-bashing, but it turns out Lowe was actually defending the bratty pop star.

Parks & Recreation star Rob Lowe will portray a lawyer in the upcoming TV movie about last summer's Casey Anthony trial, according to reports.

Lowe, who previously played Drew Peterson in the Lifetime original film Drew Peterson: Untouchable has been cast as prosecutor Jeff Ashton.

Parks and Recreation star Rob Lowe turned the football world upside down late yesterday with a series of tweets regarding Colts quarterback Peyton Manning.

Lowe stated, matter-of-factly, his shock that Peyton Manning is retiring.

Regis Philbin's replacement on ABC could be Rob Lowe, reports say.

Lowe just finished a two-day stint guest hosting with Kelly Ripa and an ABC source says the top network brass "loved the chemistry between them."

Rob Lowe has settled a lawsuit brought on by his former nanny.

Jessica Gibson had sued the Brothers & Sisters star and his wife, accusing them of sexual harassment, among other offenses, in April 2008.

You though the Rob Lowe vs. Laura Boyce feud was over, didn't you?

Far from it.

Both Rob Lowe and Jessica Gibson had important parts of their cases thrown out in court - and if you ask their attorneys, they both won.

The judge threw out Jessica's retaliation claim, but the judge also tossed out four Lowe claims - one being an allegation of defamation.
