Lindsay: Down, but Not Out

02/01/2006 at 06:00 AM EST

A little injury didn't put a damper on Lindsay Lohan's good time. While in London, the actress – who was staying in singer Bryan Adams' home – slipped on a staircase, broke a teacup and cut her leg. After bandaging the wound herself, she even got it checked out at a local hospital. Prognosis? Good enough to party: That night Lohan hit the club Tramp. "We went out together and she was fine," a friend tells us.

During her London holiday, Lohan also went out to hot spot Boujis, a favorite of the Mean Girls star. There, she ran into Owen Wilson and Woody Harrelson, her costar in the upcoming Robert Altman film A Prairie Home Companion. "She was drinking vodka and having fun," says a source. In fact, the actress had such fun that she stayed until after the club's 3 a.m. close.

Wilmer's Birthday Bash

Meanwhile, Lohan's ex, Wilmer Valderrama, celebrated his 26th birthday with more than 500 of his closest friends – including Nick Lachey, Matthew Perry, Taye Diggs and his That '70s Show costar Danny Masterson – at Los Angeles club Level. The guest of honor (whose birthday was Jan. 30) was presented with an oversized cake onstage and, a source says, told everyone "what a great party it was – not your typical Hollywood party." Except for all the celebrities in the house, of course.

Caught in the Act

• Jake Gyllenhaal (right), waiting to get in hipster bar Cha Cha in L.A.'s trendy Silverlake neighborhood. The Oscar nominee eventually decided the venue was too crowded and left before going in.

• Nicole Kidman, shopping for lingerie at Mixona, a boutique in New York City's SoHo. The sweatsuit-clad actress purchased more than $1,500 worth of lacy things, including a demi-sheer bra, an Indigo Girl vintage camisole and girl shorts, and two pairs of thigh-high black fishnets. Kidman is a regular customer at the store.
