X Factor/Fox

Demi Lovato will leave her judge's chair on The X Factor at the end of the current season, according to reports. Tonight is the first of a two-part finale for the third season of the talent show.

"She has a great time, but she's going to focus on her music next year," a source tells Us Weekly.

Lovato released her latest album, Demi in May, but hasn't toured in support of her recording yet.

The former Disney star judged the past two seasons of X Factor alongside Britney Spears, L.A. Reid, Kelly Rowland, Paulina Rubio and, her boss, Simon Cowell.

Hollywood couples could take a cue from these two!

Jon Hamm and girlfriend Jennifer Westfeldt checked some holiday shopping off their list at Barneys in Beverly Hills yesterday, and the pair weren't shy about hugging and kissing as they waited for their car at the valet.

They've been dating for 16 years now, and even though they aren't married, it seems like they're in a permanent honeymoon stage. If it's not broke, don't fix it!

The Mad Men star appeared to go commando under his jeans, which he's now famous for, so we doubt one of his purchases was boxer shorts!

Family always has your back!

Khloe Kardashian and younger sister Kendall Jenner have been spending a lot of time together recently, and the pair showed the world just how close they've become by sharing a new Instagram pic of themselves wearing matching "K Gang" hats.

"K GANG! Don't worry Kylie, we have one for you too," the 18-year-old aspiring model captioned the snapshot. That's nice she remembered to include her other sibling!

Lamar Odom's estranged wife is going through a tough time since filing for divorce last week, and she tweeted an ominous message today that seems to reference her split.

"This, in and of itself, is heartbreaking and torture to my soul. Please, I don't need the extra rumors and BS right now," she wrote on her account.

Meanwhile, their other sister Kim was busy sharing some pics of her own! The new mom attended fiance Kanye West's concert last night with pal Larsa Pippen, and wasn't the least bit shy about showing off her hot post baby bod.

"Chicago with my sis @larsapippen," she captioned the photo.

Talk about keeping up with the K clan!

Now this is what we call traveling in style!

Nicole Scherzinger arrived at LAX last night after spending time in London for the X-Factor finale and wrap party, and the former Pussycat Doll looked fierce in a fur coat and shades as she made her way through the terminal.

The singer was escorted to a waiting vehicle by her on-again boyfriend Lewis Hamilton, so it looks as if the couple is planning to spend Christmas together in the City of Angels.

Maybe there will be a shiny engagement ring under the tree this holiday season?

They're baaack!

The trailer for the new season of Teen Mom was just released, and the upcoming episodes seem to be the most drama-filled yet!

Jenelle Evans, Kailyn Lowry, Chelsea Houska and Leah Messer-Calvert deal with more pregancies, relationship drama, and even an abortion shocker as they navigate the world of teen parenting.

Kailyn is seen planning her wedding to fiance Javi Marroquin, while Jenelle gets out of jail (again!) and deals with the news she's expecting. Meanwhile, Chelsea struggles as she watches her baby daddy Adam start a family with another woman and Leah copes with raising her special needs daughter Aliannah.

We will definitely be tuning in!

She's a natural beauty!

Kate Hudson made her way through LAX last night, and the actress didn't seem the least bit worried about being caught in public with no makeup on!

The bubbly blonde kept it casual in leggings, a sweater, and sneakers, and apparently she didn't feel the need to cover her skin in a bunch of cosmetics. She has two young children at home, but miraculously no dark undereye circles. Lucky girl!

The Almost Famous star just returned from a trip to Australia to catch her fiance Matt Bellamy perform with his band Muse, but we don't think it will be long before she jets off to Aspen to spend Christmas with mom Goldie Hawn and stepdad Kurt Russell!

What feud?!

Lady Gaga and Christina Aguilera put their differences aside to perform a duet to "Do What U Want" on The Voice season finale last night, and we love how the divas wore matching gold outfits as they belted out Mother Monster's latest hit!

"I was really excited because The Voice called and said they wanted me to perform on the finale, and I obviously can't refuse. Such an amazing show! And I said 'I want to know if Christina wants to do it with me'," the eccentric singer explained to host Carson Daly.

Xtina was flattered by the invitation, and didn't hold back on her praise for Gagaloo!

"This is the first time we've ever met. When I heard she wanted to collaborate, I said of course! She's such an innovative artist and a risk taker. And as a fellow female, I have so much respect for that. And I just have to say guys, she's the most down-to-earth real person I've met. So I love you girl, and you deserve everything you've earned," the singing coach gushed.

Is hell freezing over?! Next thing we know, Mariah and J.Lo are going to bury the hatchet!

Can you believe she's 41-years-old?!

Carmen Electra grabbed dinner at RivaBella in West Hollywood last night, and the former Baywatch babe looked unbelievable in a matching top and pencil skirt that showed off her washboard abs.

The pinup shared a meal with Real Housewives of Miami star Joanna Krupa and Shahs of Sunset star Lily Ghalichi, and even though she's older than both of them, she's the biggest knockout of the bunch!
