While we, who are in the business of speculation, continue to speculate that young stars Kellan Lutz and AnnaLynne McCord are romantically involved, at least one half of the couple insists that’s not the case.

Lutz tells the New York Daily News, “I am quite single. I am happy being single. I’m very busy. I’m a relationship guy, but I recently broke up with someone who I was really in love with. And if that didn’t work, how could anything else right now?”

And to try and prove his point, Lutz made sure to show up without his rumored girlfriend on his arm at the OP campaign launch dinner and red carpet. But then again, did anyone check to seem if they were getting busy in a bathroom?
