Harry Styles Reveals Wet Hot Naked Album Cover (Photo)

"HARRY.STYLES //12.MAY.17//," he captioned both TwitPics - one showing off his wet, naked back on the self-titled album cover, and the other listing the album's 10 tracks, including new single "Sign of the Times," plus "Meet Me in the Hallway," "Carolina," Two Ghosts," "Sweet Creature," "Only Angel," "Kiwi," "Ever Since New York," "Woman" and "From the Dining Table."

Styles is launching his solo career with the help of "Saturday Night Live," where fans can catch a performance this weekend.

He's also following in the footsteps of pop superstar Justin Timberlake, a former N'SYNC boy band star who went solo, by venturing into acting. Styles will appear in Christopher Nolan's upcoming World War II drama "Dunkirk," which hits theaters on July 21.

And the role wasn't just handed over to the famous Brit. According to Nolan, Styles beat out "thousands of young men."

"When we put the cast together, we had some established names. But for the guys on the beach, we really wanted young unknowns," Nolan told the Los Angeles Times. "He's not that unknown, but he'd never done anything as an actor before. "So he auditioned. I auditioned literally thousands of young men with different combinations of young men. And he had it."
