Joey Fatone’s boy band days may be over, but that doesn’t mean the former *NSYNC star has given up on groupies all together.

Star magazine (via RadarOnline.com) reports that 37-year-old Joey, who has two daughters, Kloey and Briahna, with Kelly Baldwin, his wife of nearly a decade, was acting every bit the single man during a recent trip to Las Vegas.

According to a witness, Joey was partying at hotspot Beacher’s Madhouse without his wedding ring on when he started getting cozy with a mystery blonde.

The eyewitness claims that things heated up quickly and the pair proceeded to kiss “for 15 minutes” before taking the party elsewhere. “He had his arm around her when they left at 2 a.m,” says the source.

This isn’t the first time Joey’s been accused of having a wandering eye — over the summer, the Dancing With the Stars alum was the subject of breakup rumors, which claimed that Joey had hooked up with a fellow DWTS castmate.

Despite the speculation, Joey refuted the rumors, saying, “We’re still married … When you’re on top, people try to knock you down.”

Do you believe that Joey would be foolish enough to cheat on his wife in such a public place? Let us know your thoughts in the comments section!
