After hosting Saturday Night Live
for the fourth time, Ashton Kutcher
celebrated his success – and his 32nd birthday! – at New York City's Primehouse restaurant with the funny cast and wife Demi Moore
by his side. The group, which also included Alec Baldwin
, enjoyed two creamy cakes, and musical guest Them Crooked Vultures serenaded the actor with a rocking rendition of "Happy Birthday."
The Valentine's Day
cast toasted their film's premiere Monday night with a cupcake-filled bash at L.A.'s El Capitan Theatre. Jennifer Garner
, who attended without husband Ben Affleck
, snagged a few Crumbs cupcakes for her daughters, while Emma Roberts
snuck in a sweet treat before retreating to the VIP area with her boyfriend. Jessica Biel
held court at a table with three girlfriends, but slipped out early to catch a flight. Also there to party: Bradley Cooper
, Taylor Lautner
, Eric Dane
and Topher Grace
This singer had a fashion emergency! Josh Kelley
enlisted the aid of wife and Grey's Anatomy
star Katherine Heigl
on Monday during a shopping trip to the GUESS store at the Park City, Utah, Tanger Outlet Center. The happy couple purchased a pair of jeans for Kelley before Heigl broke off to peruse the women's department on her own.
made it a guys' night on a recent trip to West Hollywood hotspot Chateau Marmont. The Blue Valentine
star and four pals nabbed a corner table on the patio, where they dined on spaghetti and sipped red wine. But what really caught their attention was the table next to them, where a tiny Chihuahua was "singing" along to a guitarist's performance of "Sweet Home Alabama." Gosling and his buddies couldn't help but crack up, and stayed out until well past midnight.
