Tom Cruise is totally ready to shake you all night long.
To promote his role as Stacee Jaxx in upcoming heavy metal musical Rock of Ages, the 49-year-old superstar is completely transformed for the June cover of W magazine.
With long, greasy hair, intensely lined eyes and plenty of gothic jewelry, Katie's Holmes' hubby (and Suri's dad) shows off his chiseled torso -- covered with fake, elaborate tattoos -- as he poses shirtless in leather pants.
In the spread (photographed by Mario Sorrenti and styled by Arianne Phillips), the Oscar nominee does his best head-banger sex god as he sticks out his tongue and holds a guitar.
Cruise tells W that it was his wife Holmes, 32 -- plus Suri, 6 -- who helped inspire him to finally do a movie musical.
"Kate loves musicals. She sings and dances, and we kind of went through the history of musicals together. And Suri loved Hairspray," he explains. "With kids, you watch everything over and over; I watched Hairspray 15 times with Suri."
But even before signing on to the flick -- based on a hit Broadway show and also starring Russell Brand, Alec Baldwin, Julianne Hough and others -- Cruise was used to rocking out, at least in the privacy of his own home.
"You know what? I did the scene from Risky Business around the house," he recalled of his star-making turn in the 1983 comedy. "I would sing Bob Seger -- my mother worked, my sisters were out, and I’d turn the music up. I learned how to dance watching Soul Train. I noticed that if a guy could dance, he'd get a lot of attention and girls would want to dance with him. I worked very hard at imitating those moves."
