When the cat’s away, et cetera. Jessica Biel is still in Canada, filming The A-Team. Meanwhile, Justin Timberlake is still acting like “Jessica who?” whenever Biel isn’t around. The latest incident seems to have started at Hudson Terrace in New York the other night. Page Six reports that JT, his best buddy Trace Ayala, and Brett Ratner (ew) were partying with many women. After that, the boys left with a “group of girls” and headed off to the Boom Boom Room. He sounds like a single guy, doesn’t he?

Justin Timberlake partied and flirted with a gaggle of gorgeous girls the other night, sparking new rumors that he and girlfriend Jessica Biel are on the rocks.

Timberlake, who’s repeatedly denied his relationship with Biel is in trouble, flirted with a string of women as he partied with Brett Ratner at Timbaland’s album release party at Hudson Terrace on Tuesday. He later left with prolific womanizer Ratner and a group of pretty girls in tow.

A source told Page Six: “He certainly didn’t look like a man with a girlfriend. He was partying in the upstairs VIP area with his best friend, Trace Ayala, Brett Ratner and a group of girls.”

“The girls were all over him, fighting to give him their numbers, and he seemed to be enjoying it. There was one model-type blonde he chatted to for a while. At one point, a bodyguard did not recognize Ayala and kept him out of the VIP area, so Timberlake fired him on the spot.”

“Around 1:30 a.m., Timberlake left along with Ayala, Ratner and a group of girls, including the model blonde, and headed to the Boom Boom Room.”

Timberlake has been fending off rumors that he and Hollywood beauty Biel, who’s been filming “The A-Team,” are in trouble over his flirting. They put on a display of unity last month at a Jay-Z concert in LA.

They also denied a report that their three-year romance was over. Biel said in an interview last month, “You have to have a sense of humor about the whole thing.”

Earlier on Tuesday night, Timberlake attended an event at Skylight Studio and was careful to sit far away from Rihanna, who denied rumors they hooked up while working on her album.

A rep for Timberlake said, “We do not comment on Justin’s private life.” A rep for Biel didn’t get back to us.

Two things: first, the most interesting part of the story was when JT fired the guard “on the spot” for not recognizing Trace Ayala, who I couldn’t pick out of lineup either. Secondly, I don’t really think what Jessica and Justin did to fight the breakup rumors should be called a “display of unity”. Jessica literally dragged JT out for a few photo ops, and then gave a few interviews denying the rumors while JT stayed silent. I think they really are broken up for real, or Jessica is letting him see other women.

Oh, and one other thing – Lainey Gossip mentioned this in a post yesterday: “Pippy hit up Timbaland’s album release party and may or may not have paid a visit to a brunette piece he’s keeping in NYC on the site. That’s the rumour, and while it’s not slamdunk quite yet, some insist it’s been common knowledge for ages dating back from when Lilo ratted him out last summer.” So, JT has Biel, a brunette on the side, and a blonde model in the Boom Boom Room. This is better than playing Clue. Also – doesn’t the photo below look like The Douche Convention?
