When Should Stars Stop Partying?

Steven Tyler's Aerosmith bandmates are worried about the frontman's erratic behavior.

"He's got some bad influences in his life right now and he's making poor choices," drummer Joey Kramer told People. Aerosmith guitarist Brad Whitford added, "His behavior is spinning out of control."

How do you tell a 61-year-old man to grow up? Tyler's condition isn't really anything new. The music world and Hollywood are full of aging lads who don't know when to take off the party pants. PopEater takes a look at a generation of celebs who should let the party bus leave the station without them.

David Hasselhoff

The Hoff, 57, loves his liquor. His daughter caught him shirtless, chowing down on a hamburger and drunk as a skunk in 2007. It would have been just another night for the Hasselhoffs except that the tape made its way to the Internet. David Hasselhoff admitted a relapse and said he was working on his recovery but Hoff was reportedly tipsy again at the MTV Europe Music Awards in Berlin earlier this month, grabbing onto a wall for support and slurring his words onstage as he presented the Best Rock Award to Green Day.

Keith Richards

Rolling Stone Keith Richards, 65, reportedly got so drunk on the set of "Pirates of the Caribbean" in 2006 that the director had to prop him up. "If you wanted straight, then you got the wrong man," Richards said. Earlier that year Richards experienced a concussion after falling from a palm tree in Fiji.

Mel Gibson

Since Mel Gibson, 53, went on his drunken anti-Semitic tirade when he was pulled over for driving while intoxicated in 2006, he has managed to keep his party in his pants. But every once in awhile Mel hits the gossip pages for having one too many at Nobu in Malibu. Thankfully he has stayed away from the wheel.

Kiefer Sutherland

Jack Bauer allegedly racked up a $700 bar tab with the "24" crew in San Pedro, CA earlier this month, before 1pm! But that's nothing compared to whenKiefer Sutherland, 42, ties one on with his band, in sessions that have included break-dancing and head-butting and one instance of one-on-one combat with a Christmas tree.

Nick Nolte

Nick Nolte, 68, has one of the most famous celebrity drunk driving mug shots of all time, probably because he looks like a cross between a hobo and the Big Kahuna. Nolte may not party more than the rest of us but unfortunately has always seems to get stuck talking to reporter-folk after he's had a few too many beverages.
