Kate Hudson stopped for a tray of Valentine's Day goodies in LA this morning. Her boyfriend, Matthew Bellamy, joined her for the trip after the duo stepped out together at yesterday's Grammy Awards. Matthew was one of the night's big winners with his band, Muse, and he thanked pregnant Kate during his acceptance speech. The couple apparently don't plan on finding out the gender of their baby, though they have discussed names for their future child.

Katherine Heigl left her NYC hotel with her Valentine, Naleigh, on Saturday. The movie star mom has been focused on another holiday, though, as she shoots New Year's Eve in the Big Apple. Katherine was a late addition to the cast and stepped in to take over for Halle Berry, who left the project to focus on her custody battle with ex Gabriel Aubry. Katherine's film is nonetheless packed with celebs, including Zac Efron, Jessica Biel, and newly single Sienna Miller. It will also reunite her with her Killers costar Ashton Kutcher. Katherine and Ashton's collaboration didn't fare too well with audiences, but he enjoyed a big box office success with his latest comedy No Strings Attached.

Jude Law changed in and out of a hazmat suit on the set of Contagion in San Francisco yesterday. The newly single actor is spending Valentine's Day focusing on work while his former girlfriend and frequent beach companion, Sienna Miller, is rumored to be hanging out with Robert Pattinson's best friend, Tom Sturridge. Jude is rolling solo on this loved up holiday, but there are plenty of women who'd like to spend a romantic weekend with him. His stay in the States will extend into later this month so he can join Reese Witherspoon, Sandra Bullock, and Halle Berry as presenters at this year's Academy Awards ceremony — don't forget to fill out Buzz's Oscar ballot for your chance to win a big screen TV!

Nicole Richie celebrated the launch of her Spring Summer Winter Kate and House of Harlow 1960 collections on Friday night in East Hills on Long Island. The boutique Singer 22 hosted the event, where Nicole rocked some jewelry and a dress of her own design. She also happily signed copies of her books for fans, even indulging in a little shopping during the soiree. It was the second party thrown in honor of the designer during Fashion Week, but she made an early exit from the festivities. The mother of two headed home to LA just in time to celebrate Valentine's Day with Sparrow, Harlow, and Joel. She'll be jetting right back East, though, to cohost The View tomorrow morning.
