Sexy Exies Kellan and AnnaLynne Cool It in Miami

Another on-and-off Hollywood couple keeps us guessing

Kellan Lutz and AnnaLynne McCord both coincidentally hosted their own New Year's Eve bashes in Miami last week…down the street from each other.

Lutz was staying at the über-posh Shore Club in South Beach, while AnnaLynne posted up at the W a few blocks away.

It's hard to keep up with the on-off couple who split in summer but keep reuniting.

Even though Kel insisted to us back in November that he was single and never dated McCord, it looked as if he was rather taken during his boys' trip in South Beach...

Lutz hosted his NYE bash at new Miami club Klutch. He looked superdelish, as usual, in an all-black suit, with his hair lighter and slightly curlier than we're used to. Is this the new metro crap, or what? Kellan was with a group of his pals in the VIP section and had plenty of girls trying to get in to hang with the Twilight star. So did K.L. bite?

Nope. We're told he didn't lock lips with any of the hopeful chicks there at midnight...or the whole vacay! According to sources "he just hung with his guy friends" the majority of his trip to South Beach.

That is, when AnnaLynne wasn't sneaking in to see him...

After finishing her hosting duties at the W on NYE night, she ended up over at the Shore Club, presumably hanging with her vampire beau.

"[Kellan] kept asking people about what AnnaLynne was up to and vice versa," says our source of the two lovebirds during their trip.

McCord was also spotted leaving Kellan's hotel Saturday afternoon.

A.M., looking adorable donning her au naturel curly hair and a white James Perse shirt was trying to leave the hotel incognito, but found a few people waiting for her out front by the valet.

"Oh s--t, paparazzi," McCord said, a bit panicked outside.

She got flustered and tried to hide behind a pillar to avoid being spotted with the Twilight hunk, who was casually standing outside with her group also.

So far sounds like New Year's Eve went better than last year, when Kellan supposedly kissed another girl in front of AnnaLynne at midnight down in Miami.

Don't think these two cuties are exactly back together just yet, but if Kellan's wooing efforts are working we don't see how she can resist!
