15 year old Miley Cyrus sure does move on quickly.  Just last month it was rumored that she was dating her 22 year old back up dancer, Marshall, and now she is being linked to 17 year old Lucas Till.

Lucas plays Miley’s on screen boyfriend in Disney’s Hannah Montana movie.  A set insider claims that Miley personally picked Lucas for the role and they immediately hit it off.  The set insider stated that,

The moment Miley saw Lucas’ photo, she knew he was perfect to play her on screen love.  Once they began shooting, she totally fell for him.  It was as if she decided  she wanted him and she would have him-Lucas had no choice in the matter.

And apparently Miley is not afraid of displaying her affection for Lucas.  According to the same source,

She is always cuddling up to him and  kissing him on the cheek.  I’ve even caught them sneaking behind the trailers in full-on make-out sessions.

I guess you could say that this is typical teenager stuff, sneaking off to make-out with your boyfriend, but then again there is no such thing as typical in Hollywood.  We can only hope that she doesn’t end up pregnant at 16 like Jamie Lynn Spears.  Check out this clip of Miley interviewing Till.
