LINDSAY'S BUSY NIGHTLIFE
Lindsay Lohan seems to have fully recovered from her bout with exhaustion—and her recent breakup with Wilmer Valderrama. On Nov. 15 she joined Justin Timberlake and Nicky Hilton at Timberlake's restaurant Chi, then later walked across the Sunset Strip to Fenix at the Argyle to mingle with actor Danny Masterson (That '70s Show) and his date, socialite Bijou Phillips. Two nights later Lohan went to the L.A. hot spot Concorde; the next evening she hit the ever-popular Prey, sharing a booth with the Hilton sisters and Nicky's actor beau Kevin Connolly, Lohan then capped off a busy week by turning up at Avalon Nov. 19. There she danced on the VIP stage, barely 100 feet from Valderrama, who was sharing a booth with Masterson. Although Lohan and Valderrama saw each other, the two never interacted. Instead, she spent much of her time chatting with another clubgoer, Christina Aguilera.

AN ABOVE AVERAGE COUPLE
After two failed TV relationships, reality star Adam Mesh has found real love... with the girl next door. Mesh, 29, who starred in both the original Average Joe and its sequel Average Joe: Adam Returns, is dating Jessica Malca, a 23-year-old financier who lives in his building. "My roommate [spotted her], and he was like, 'That girl is so for you,' " says Mesh, who brought Malca to Gotham Magazine's Nov. 17 anniversary party in New York City. Mesh told us he and Malca started seeing each other last May, after Adam Returns aired (and after he broke up with that show's winner Samantha Trenk). "It's nice to be with a real girl who likes me for who I am," says Mesh. "I'm really happy. I think she's the one."

CRASHING CHLOE'S BASH
Chloë Sevigny held a private 30th-birthday party at the Manhattan club NA Nov. 18. Sequestered in a back room, which was blocked off by security guards, the actress welcomed prescreened pals including Sean Lennon, Tatum O'Neal and Chris Noth. That is, until Sean "P. Diddy" Combs rolled in around 2:30 a.m. with his own team of bodyguards. An NA regular, Combs swept past Sevigny's security and commandeered a booth in the actress's party space. The rap mogul surveyed the scene but didn't seem to notice the roomful of balloons or birthday cake. Then Combs headed for the door at 3 a.m., leaving as abruptly as he arrived.
