Cristin Maher

As if we didn't know already, Amanda Bynes has officially gone off the deep end. However, the psychiatric powers that be are now involved. The wig-loving actress, who has become infamous for her bizarre, often offensive and sometimes dangerous behavior, has been placed on 5150 psychiatric hold after she lit a fire in a stranger's driveway.

Kristen Stewart is camouflaged out on the set of her new film 'Camp X-Ray.' The actress donned Army fatigues and combat boots while shooting the new Guantanamo Bay-inspired movie in Los Angeles on Wednesday, July 17.

Congratulations to Adam Levine and Behati Prinsloo, who just got engaged!

Taylor Lautner's acting resume runs a whole lot deeper than just 'Twilight.' His latest film project is 'Tracers,' due out in 2014, where Lautner plays a bike messenger / parkour enthusiast targeted by the mob. (Hmmm, sound familiar? 'Premium Rush'? Anyone?)

John Mayer has really turned his act around, and his latest "awww"-worthy deed might just be his kindest act yet.

'Vampire Diaries' actor Zach Roerig is going through some major drama in his personal life right now. Not only does the 28 year old, who plays Matt Donovan on the CW series, have a 2-year-old daughter, but he's also in the midst of a fierce custody battle over the child with his ex-girlfriend, Alanna Turner, who is currently serving time in prison.

It looks as if Ashlee Simpson has found a new "baby love" to cuddle up with. The singer/actress/fashionista was recently spotted getting all love-y dove-y with Evan Ross, the son of iconic Motown songstress Diana Ross.

Avril Lavigne showed up to the 2013 MuchMusic Video Awards looking so happy with her fiance, Nickelback frontman Chad Kroeger, but she looked even happier up on stage when she was performing her latest hit 'Here's to Never Growing Up.'

Pop stars from around the world busted out their best duds for the red carpet at the 2013 MuchMusic Video Awards. Here, you can see of some of your favorite singers, like Taylor Swift, Demi Lovato and Ed Sheeran, as they posed for red carpet pictures prior to the 2013 MuchMusic Video Awards tonight (June 16) in Toronto, Canada.

While Pink has rocked virtually every hairdo under the sun, she tends to stay on the shorter side of the strand spectrum. So, of course we got excited when we saw these pictures of 'The Truth About Love' singer rocking long hair in Venice Beach over the weekend.

Taylor Swift is looking to settle down -- and no, we don't mean romantically. The 23-year-old '22' singer is on the hunt for a home of her own, and Swift's most recent house-seeking adventures took her to the very swanky New England town of Watch Hill, R.I.

Tonight (Feb. 10) in Los Angeles, stars gathered at the Staples Center for the 2013 Grammy Awards. As you can see from these performance pictures and show pictures from the 2013 Grammys, it was a night of mingling, laughs, remembrance and of course, great, great music.
