Kristin Cavallari was spotted leaving M Cafe on Melrose today, and the former Hills hottie showed off her glowing skin -- and that fabulous 5.2 carat rock! -- when we snapped her picture.

While Kristin seems thrilled that her engagement to NFL star Jay Cutler is back on, we're sad to report that she won't be spending her whole holiday vacation with her beau. "I won't be with him Christmas Eve or Christmas, but I'll be with my mom and that whole side of my family," Kristin told Us Weekly on Monday. "Jay, unfortunately, is playing in Green Bay on Christmas Day." Boo! This is the first holiday that the couple has spent apart, "so obviously it won't be great," she added. "But it is what it is."

But hey, there's still New Year's Eve, right? Hopefully these two get to stand under the mistletoe for that one!

Pregnant starlet Hilary Duff looks so cute and comfy in her moccasin boots!

The Disney darling, married to hockey player Mike Comrie, hit the shops on Melrose Avenue in Hollywood to grab some Christmas gifts. Hil's outfit isn't very festive, but you can't go wrong with basic black.

As for her growing baby bump, Duff recently told E! News:

"I think it's such a miracle. I feel so lucky that I've had an easy pregnancy and hope it stays that way. I think feeling the baby move and getting those little kicks…seeing it happen through your shirt or looking at your belly, it's like, wow, there's a life inside of me. It's a piece of my husband and me and it's really wild. It's really exciting to think about the future and also a little scary…but so exciting at the same time.

No one can deny that Hil is beaming. Adorbs!

Pete Wentz has plenty to smile about -- he's got a beautiful son, a model rebound girlfriend and he even seems to be on good terms with his ex-wife, Ashlee Simpson.

Yesterday we spotted the Fall Out Boy rocker shopping in Beverly Hills, and in case you're wondering where his lady love Meagan Camper was, it seems like he was doing a little Christmas shopping for her! So what was he looking for, exactly? Click after the jump to find out!

Angelina Jolie is lovin' life in the kitchen with her man Brad Pitt!

The 36-year-old director/actress sat down with Anderson Cooper to discuss her cooking experiences with Mr. Pitt.

Jolie, who is promoting her directorial debut In the Land of Blood and Honey, tells Cooper:

"Brad and I decided we were actually going to make the turkey and we were very successful and very proud of ourselves. We did it!"

It's no secret that Jolie and the Moneyball actor take their six kids traveling around the world. Angie adds:

"Fortunately, my kids love to travel… they're very worldly. What I love is that they can be in New York in a hotel in Manhattan and think it's so cool, and then I can bring them to the middle of Kenya and drop them in a tent with no TV and no nothing, and they're just as happy."

Angie's appearance will air on Anderson next Monday.

Giuliana Rancic underwent a successful double mastectomy and reconstructive surgery last night for her breast cancer, according to E! Online.

Husband Bill Rancic told the site, "G is doing really well ... Her surgery lasted about four hours and the doctors were very pleased with the result. She had a little bit of pain through the night but is feeling much better this morning and was cracking jokes." Giuliana added, "I want to thank all the viewers and fans for their support and prayers. The tweets and notes have not gone unnoticed. I am very grateful."

The E! News host was diagnosed with breast cancer three months ago, and she recently told The Today Show's Ann Curry that after some careful consideration, the radical procedure was the only option for her. "For me, it was important to get the cancer out," she said. "That's what I wanted to do, just get it out ... At the end, to be honest, all it came down to was just choosing to live, and not looking over my shoulder for the rest of my life."

Today Demi Moore went to her fav nail salon yet again, and the 49-year-old actress was in such a rush to get to her car, she dropped her pricey wayfarers and didn't even bother picking them up!

Sadly, it seems like her divorce from Ashton Kutcher is really taking a toll on her once stunning looks -- not only has she dropped a significant amount of weight, but she appears to have aged ten years in the last ten weeks. Of course, she's always looked about a decade younger than she really is, so now that she finally looks every other late fortysomething out there, it can't be that bad, right?

While Demi is no longer wearing her wedding ring, she is still wearing her Kabbalah bracelet, which is interesting when you consider Ashton was recently spotted without his. Demi was the one who attempted to use the religion to save her marriage, trying everything from counseling to camping retreats, so it seems like she's a true believer!

Miley Cyrus is saying she did NOT have her breasts enhanced!

The Hannah Montana star raised eyebrows when she stepped on the red carpet of the CNN Heroes tribute wearing a plunging Robert Cavalli gown.

After reports spread that Miley had gone under the knife, the 19-year-old singer Tweeted:

"Thank you for the compliment, but these babies are all mine. I wish [people would] realize you don't have to be fake to be beautiful! I'm 19! BOOBS GROW, PEOPLE!"

Oh, Miley!

Lindsay Lohan arrived to the Airport Courthouse ten minutes early for her probation hearing.

Judge Stephanie Sautner seemed very pleased with Lilo's progress telling the 25-year-old actress, "Miss Lohan, you have actually done your work."

The judge mentioned that Linds had completed twelve community service days ahead of schedule. She also added that the morgue was happy with Lilo's work saying "At least as pleased as a morgue can be."

Judge Sautner revealed that Lindsay also attended an extra therapy session ... five in total.

Lilo's recent trip to Hawaii was addressed in the courtroom, and it turns out, she was able to go out of state to celebrate Ali's birthday.
