Christina Aguilera was in a great mood when we snapped her taking care of her holiday shopping at Fred Segal over the weekend. And not only that, but she wasn't wearing her usual face full of makeup and she still looked fabulous!

On Friday Xtina and beau Matt Rutler took her son Max to meet Santa, and if you're wondering what's going on with her ex-hubby Jordan Bratman, rumor has it he's romancing none other than Heather Graham!

According to Star, the actress "was all over" Jordan at a November 25 house party. "Heather was aggressively putting the moves on Jordan, who was lapping it up," an eyewitness tells the mag. "She was so excited when she got to the party that she was actually nervous to talk to Jordan. Although it took Jordan all night to ask for her number, he walked out with her digits – and is now trying to figure our where to take her on their first date." Interesting!

We're not sure what the theme of the party was, but Violet and Seraphina sure look adorable!

Over the weekend Jennifer Garner took her two daughters to a pal's birthday bash in Brentwood, and we're guessing hubby Ben Affleck is happy to have her back in town!

Jen spent most of last week in New Orleans wrapping up shooting on The Dallas Buyers Club, and from karate to school, Ben was on double duty with both of the couple's oldest children. Of course, we're sure he's happy to have her back for the holidays and not just because she's usually the one looking after their three kids!

Kat Von D and Deadmau5 (nee Joel Zimmerman) are engaged!

"I can't wait for Christmas so.... Katherine Von Drachenberg, will you marry me?" the deejay tweeted yesterday. Her reply? ""Mi corazon! Thank you all for the lovely congratulations! Please excuse me while I go squeeze the hell out of my fiance!"

Deadmau5 then replied, "Holy f*cking sh*t. I'm engaged and stuff! Thanks for the well wishes and support from the horde and everyone else! Brb while i spend the rest of my evening with my future wife." The deejay posted a photo of the engagement ring, and it looks like it'll be the perfect fit for Kat:



While we're happy for the couple, we are a bit surprised, as they've only been dating for 4 months and already had one major split. In November, Kat confirmed that the two had broken up and tweeted, "Man, I sure was wrong. But at least he made it a no-brainer to break that off. Lesson Learned ... Clarification: Deadmau5 and I are no longer together." A few days after their Twit split, we spotted the two together, and on Friday they were joined at the hip after a lunch date.

Can you believe she's FORTY!?

Dita Von Teese attended her perfume launch at Fred Segal on Saturday, but she was a little bit late after a minor wardrobe mishap. Dita tweeted a photo of her cat Aleister sitting on her outfit and wrote, "Slightly late to my perfume event at Fred Segal because this happened to my freshly pressed vintage Mugler suit."

Oops! Looks like a lint brush might have solved her problems, because when we snapped her picture, she looked amazing ... and we didn't see a single cat hair on her!

Paris Hilton dined at Mr. Chow in Beverly Hills with beau River Viiperi and her parents on Saturday night, and the heiress slipped into a super hot red dress and fishnet stockings. That's one way to get into the holiday spirit ... and get our attention!

After dinner, P and River went home to watch movies (Elf and This Is 40, if you must know), and River tweeted, "After a Wonderful Dinner W/ my Baby Love @ParisHilton, @KathyHilton & Rick Hilton @Mrchows, Time to pack & watch a Movie #Aspen #DoubleDate." Sounds like a blast!

Mad Men star Jon Hamm and longtime girlfriend Jennifer Westfeldt were spotted holding hands in Los Feliz on Saturday afternoon, and we can't believe these two have been together for 14 years! That's practically an eternity in Hollywood!

However, it doesn't look like Jennifer is going to be walking down the aisle anytime soon, as reports popped up earlier this fall that her beau has no interest in making things official.

"Jon and Jennifer have talked marriage before, but he's always shied away from it," a source told the National Enquirer. "Now, Jennifer's at a stage in her life when she wants stability, security and a family. So she worked up the nerve and told Jon it was time to get married or she was moving on. [But] Jon angrily told Jennifer that a wed­ding was not in their future. He said, 'If you want to get married, go right ahead. There's the door. Go find someone else to marry because it's not going to be me!'"

Um, yikes! But do we really believe that?

That is, a hug and a quick smooch on the cheek from a very attractive flight blonde attendant with a bottle of beer in her hand!

Over the weekend Johnny Depp was snapped taking off in his private jet, and we're not sure where he's headed, but he's definitely not bringing his kids with him! Maybe he's meeting up with rumored lady love Amber Heard for a romantic getaway?

Last night a bra-less Rihanna and a girlfriend went to Las Palmas in Hollywood, and the R&B superstar was NOT in the mood to have her photo taken. Maybe she was feeling a little stressed over work and the drama with her on-again/off-again beau, Chris Brown? That's our best guess...

After spending the day at the studio doing voiceovers for the upcoming animated flick Happy Smekday, RiRi tweeted, "Had a blast today! So weird recording for animation, but I get to keep my accent! AND it's PG, which mom should be happy about! Brrrap!!" So what was next on her agenda? Party time! Rihanna wrote, "Mama gets to blackout TONIGHT!!!!"

Hope she had fun!
