When you've got it, flaunt it!

Aerosmith front man Steven Tyler couldn't keep his shirt on as he revealed his sexy abs in an unbuttoned shirt while signing autographs for fans in Hollywood, on Monday afternoon. But when a curious fan asked if her had any advice for Britney Spears' new gig on X-Factor, Tyler replied:

    "Britney Spears, up your meds girl! It's a hell of a ride."

The 64-year-old rock star recently revealed that he didn't really enjoy his time as an American Idol judge, although the huge paycheck couldn't have hurt, but apparently Tyler used the gig as a distraction from his feuding Aerosmith bandmates, who have since reunited.

Steven reveled in an interview with Rolling Stone mag: "It was something to do while the storm blew by, to be honest. The show's about kids and what you do to nurture their talent. They wanted me to take the p*** out of the kids and I don't have that in me. That's not what I'm about. That's more about that other guy. Not me."

Aerosmith is gearing up to release their new album, Music From Another Dimension, in November.
