Kellan Lutz and Sharni Vinson Split Up!

They've been an item for the past year and a half, but now Kellan Lutz** and Sharni Vinson** have decided to go their separate ways.
The "Twilight Saga: Breaking Dawn Part 2" hunk and his Australian actress gal broke up earlier this month, according to a source close to the couple.
Back when they first started dating, Kellan was head-over-heels for Vinson, whom he met during a reading for "Step Up 3D." Interestingly enough, Lutz never actually appeared in the flick, but he never forgot Sharni, either!
He previously told press, "She's a happy person, which really just clicks with me. It's just great to have someone you can smile with all the time. It's really special."
