Vanessa Minnillo, who, after months of speculation, recently broke up with Nick Lachey, has wasted no time getting out there on the singles scene.

An insider tells Life & Style she saw Vanessa at the Reebok Easytone party in Beverly Hills on June 23. "She certainly wasn't moping in the corner or looking upset over her breakup at all," says the insider. "I saw her talking to three or four really cute guys. She totally seemed to be flirting and didn't look like she was upset or anything."

The insider says that the former Total Request Live co-host appeared to be having fun hanging out with a girlfriend. "Vanessa doesn't strike me as the type of girl that will remain single for long. She looks like she's on the prowl and that she'll stop at nothing to get her prey."
