Rumors have been flying that Miley Cyrus is dating (or at least hooking up) with "Twilight" actor Kellan Lutz ever since the two were photographed getting off of the same private jet in Miami together, and recently Lutz was caught on video with an answer the big question, E! News reports.

In a new paparazzi video from X17Online, Lutz is captured on film signing autographs for fans in L.A. and asked about his alleged relationship with the 21-year-old pop princess.

"You guys are stupid," Lutz said with a smile before clarifying, "No, I'm happily single, I am very focused on work." That includes his next big screen role in next year's "Hercules: The Legend Begins," and "The Expendables 3," which he is currently filming.

Yesterday, an insider told E! News that Cyrus and Lutz are "definitely not a couple," so perhaps they just happened to be sharing the same jet together, or maybe the two are hooking up in secret, as some fans speculate.

Either way, Cyrus has not commented on the rumors, though she has been linked to a number of men over the past few months since announcing her split with Liam Hemsworth, including "Good Charlotte" guitarist Benji Madden, producer Mike Will Made It and Theo Wenner.
