JON BON JOVI HAS LED a charmed life. From rock megastar to budding actor, he seems to have made all the right choices (dodgy haircuts aside). And his latest film effort puts him up alongside a stellar cast in the U-boat drama, U-571, which opens today. Bon Jovi (above, third from right) was born John Francis Bongiovi on March 2, 1962, in Perth Amboy, New Jersey. Like Bruce Springsteen before him, he found his way out of Jersey through music, first in 1983 by cutting a demo at New York's Power Station studio - owned, incidentally, by his cousin Tony. Next up came the recording contract, the name change, the new band and the big, big 1980s hairdo. Although successful from the outset, the band Bon Jovi really hit the heights with their 1986 release Slippery When Wet - a classic in the soft metal genre - which sold more than 10 million albums. Jon Bon Jovi's first brush with Hollywood came in 1987 when he tried his hand at writing songs for the soundtrack to Mel Brook's Spaceballs. From there he went on to his first acting role, a cameo in 1990's Young Guns II. He also wrote the soundtrack for that effort, and the hit song Blaze Of Glory brought him an Oscar nomination for best song. But the acting bug had bit hard and roles in The Leading Man, Little City and Homegrown followed before his big break came with U-571. And as if rock stardom and a silver screen career weren't enough, Bon Jovi was chosen by America's People magazine in 1996 as one of the 50 most beautiful people in the world.
