Seriously? No way in hell! These two can NOT be dating. I won't stand for it!

15-year-old Disney superstar Miley Cyrus was spotted at the Cheesecake Factory in Hollywood this weekend with a big piece of man candy on her arm. Yes, her fam was with her, too. But still! Please tell me this guy is just her co-star... who also just happens to look like he's 25? PLEASE!

Oh no she didn't! Flashing us the peace sign while grinning? This girl loves the attention... maybe too much?

UPDATE! Is this Justin, an eliminated contestant off Nashville Star (kind of the country version of American Idol, hosted by Miley's dad Billy Ray)? He sure looks like it!

But even if the Louisiana native - who used to support himself as a model - is just hangin' with the Cyrus fam, how come he and Miley look so close?
