That didn't take long.

Just days after her split with Nick Lachey, Vanessa Minnillo has reportedly moved, at least for a few hours on Saturday night.

According to sources at Radar Online, the former MTV VJ made out with with actor Topher Grace at Family Guy creator Seth MacFarlane’s Los Angeles home over the weekend.

MacFarlane was hosting a party that included an outdoor casino, around which Minnillo and Grace were spotted flirting, whispering to one another and exchanging phone numbers.

From Nick Lachey to Topher Grace: Upgrade or downgrade for Vanessa Minnillo?

"Before long they were on the dance floor and putting the ‘dirty’ in dirty dancing," a witty witness said. "Vanessa took off her shoes and held them in one hand, wrapping her other arm around Topher’s neck and the next thing we knew she was kissing him on the neck! They [later] started making out right on the dance floor!”

Around 1:30 a.m. the pair left the party... together!

Somewhere, Lachey is penning the lyrics to his latest soul-crushing ballad. Sorry, dude.
