This is one couple we'd love to see more of, so hopefully they'll bring their rekindled romance home to Hollywood!

90210 hottie AnnaLynne McCord and her on-again/off-again boyfriend Kellan Lutz are back on, and it sounds like the couple heated things up in Miami over the weekend! AnnaLynne and Kellan attended the Hydroxycut Advanced Suite at Michael Bay’s Florida mansion on Saturday night, and a source at the event told X17online exclusively:

    "I heard Kellan and AnnaLynne had been hanging out right before they showed up to the party, and it looked to me like they're definitely back on. They were flirting and laughing the entire night, and they appeared very comfortable together."

Though AnnaLynne has recently been spotted out with a cute brunette dude, another source close to the couple tells X17online that AnnaLynne and her man are in fact back together.

Maybe she got a glimpse of his smokin' hot Calvin Klein ads? That'd be enough to send me running back into his big buff arms!
