Rocker Tommy Lee had to step in to separate his ex and his current girlfriend when Erin Naas and Kimberly Stewart clashed in a nightclub last week.

Lee and Stewart were hanging out at Los Angeles' Hyde nightclub celebrating the birthday of the socialite's brother Sean, when Naas showed up with friends.

In Touch Weekly reports the rock star had to separate the two women after Stewart took exception to what appeared to be Haas' interest in her man.

A fellow reveller tells the publication, "Kimberly freaked out because Tommy walked right over to Erin. She started making faces and then threw a lollipop at Erin's head!"

Lee stepped in to calm the women down, and forced Stewart to apologize.

A pal insists Stewart had nothing to fear: "Erin has zero interest in Tommy other than as a friend."
