Blake Lively and Penn Badgley both partied hard on New Year's Eve ... just not with each other. Both made E! Online's "Party Girl" report, however!

Penn was very hands-on with a girl who looks nothing like his ex, dancing (and making out) with an exotic-looking brunette at Liv nightclub in Miami.

Moreover, they were standing on the tabletops for all the see!

The newly single guy was living it up alongside co-star Chace Crawford, Matthew Morrison, JC Chasez, Lauren Conrad, Kyle Howard and others.

As for why Penn was hanging with that random crew (minus Chace), a source says they share the same manager, who flew them down to party.

Ah, that makes perfect sense. That's how we choose where and with whom to go clubbing, am I right guys? As for his former lady love Blake ...

The blonde beauty was hanging tight with Florence Welch from Florence + the Machine (above), who performed at Marquee nightclub in Vegas.

They were there for the Cosmopolitan Hotel's star-studded opening.

The girls were spotted arm-in-arm post-performance. Unlike Penn, Blake wasn't interested in anyone from the opposite sex during her NYE revelry.

It's okay. She's got Ryan Gosling waiting in the wings when and if she's ready to move on. And our own Gossip Guy. Call him Blake, he's waiting.
