Robert Pattinson and Kristen Stewart got cozy in a New York City club Thursday night, a source tells

While Kellan Lutz, Peter Facinelli, Elisabeth Reaser, Ashley Greene and Nikki Reed hung out at an Alizé-sponsored affair at The Box club, the couple snuck to SoHo House with Taylor Lautner.

"Taylor, Kristen and Rob didn't come to [The Box] because they were skittish about the crowd," a source tells "Extra."

At 1:30 AM, the two ditched Lautner and met up with Joan Jett at another club, Avenue, where they were flanked by security.

"They sat very close to each other [and] looked very happy together. They chatted together the entire time," the source tells Us, adding that he drank Amstel Light, and she drank Belvedere Vodka.

The pair left at 3 AM "holding hands," the witness goes on.

Meanwhile, back at The Box, Reed arrived with beau Paris Latsis.

"They were whispering into each other's ear and Paris kept leaning over the balcony to check out the fans below," a witness tells "Extra."

Kellan Lutz had an easier time getting into this party. The actor "rolled up with friends and some female models and seemed to be the most energetic of the crew. He was chatting and bopping to the music with Ashley Greene, who came with girlfriends."

"Gossip Girl" couple Ed Westwick and Jessica Szhor arrived around midnight, where they hung out with Ashley Greene.

"Jessica seemed exhausted and wasn't as into the party while Ed was walking around chatting with people and drinking champagne," the witness tells "Extra."

Fergie "made a low-key entrance around midnight after the Victoria's Secret fashion show, followed by [Black Eyed Peas band-mate] Taboo, and the two went to a VIP table that was blocked off by bodyguards," adds the insider.
