Red Hot Chili Peppers' Anthony Kiedis Goes Shirtless at 50—and He Looks Great!

Singer was seen in Hawaii riding a bicycle

It's hard to believe it from this shirtless pic, but Anthony Kiedis is 50-years-old.

The Red Hot Chili Peppers frontman was spotted on Sunday, Oct. 6, showing off his tattooed toned arms and muscular torso while on vacation in Hawaii. And while he is looking as fit as ever, he was in a slightly stressful situation. The rocker locked his keys in his car and started riding a bicycle to get some assistance. Luckily, he was finally able to open his car door with the help of a stranger.

Sans shirt, a mustached Kiedis wore black shorts, sandals and a colorful trucker hat.

Next up? Kiedis and band member Flea will serve as hosts and also play at a benefit concert at the Silverlake Conservatory of Music on Oct. 30 in California. According to Billboard, Flea founded the Silverlake Conservatory of Music in 2001, which "facilitates music education and offers music lessons and scholarships." Neil Young will also perform.
