We spotted "Twilight" star Kellan Lutz going for a run with his dog around his L.A. neighborhood earlier this week.

Lutz, who was wearing all black and wearing headphones, seemed to finish his run with an intense sprint down the middle of the road.

Well, ladies, the rumor is Kellan is currently single! The actor and "90210" star Annalynne McCord have split after two years together, according to reports. Representatives for the two stars have yet to comment on the break-up story.
