Hilary Duff and Haylie Duff
, sharing a sisters' night out with older sib Haylie
at Teddy's inside the Hollywood Roosevelt Hotel
. The starlet and her sister – plus several friends – made an energetic arrival, and stayed revved up all night: Hilary danced provocatively to Britney Spears
's new single, "Womanizer," and offered her girlfriends little lapdances, an onlooker tells us. And the sisters were in for the long haul, talking and dancing until the club closed. Also there: Frankie Delgado
and Doug Reinhart.
, celebrating her friend Molly's birthday at Las Vegas's TAO
Asian Bistro with champagne toasts, sushi and Kobe beef after hanging out the night before at Lavo. The actress surprised her pal with a cute round cake, which they dove into at the table. Full from dinner, they couldn't finish the dessert and took it back to their rooms for later.
, stealing a snuggle with Gerard Butler
at the opening of Shin Korean BBQ in Hollywood. For much of the evening, the two – who know each other and are friendly, sources confirm – were spotted hanging out separately. Butler was mostly socializing with his male friends at the party, singing along to "Sweet Home Alabama" and, at one point, tending bar for partygoers. Later, though, the pair met up and "they were flirting innocently," a source tells us.
, perching in a luxury suite to watch the L.A. Dodgers play the Philadelphia Phillies at L.A.'s Dodger Stadium. The American Idol
host was with two women and "arrived early and bought some gear at a souvenir store," says an observer. Ever the worker bee, Seacrest was spotted typing away on his BlackBerry during key moments of the game. The night before, he held court at his regular table at Hollywood's Beso for a pal's birthday dinner at the restaurant, which he partially owns (along with Eva Longoria Parker
). The Idol
host even joined in a rousing rendition of "Happy Birthday." Wonder how Simon
would rate his performance?

a Godiva mousse dessert, followed by a kiss on the lips at her Burger Bash event in Brooklyn.
