Wonder what Britney will look like at age 50? Then check out a new short film called "Britney 2032".

The short,directed by Marc Sedaka (son of '60s and '70s pop star Neil Sedaka) finds Britney promoting her autobiography, "Oops! I'm Still Alive", at the age of 50 and still wearing her "Baby One More Time" cheerleading outfit, Music 365 reports.

No fans arrive at Britney's autograph session except for one man who asks her on a date.

"I could have married Prince William, you know," she says. "He asked me."

Then, a chubby middle-aged Justin Timberlake shows up and convinces Britney to join *Nsync and the Backstreet Boys for a reunion concert.

If you'd like to see the movie yourself, it can be downloaded at the official Warner Bros. website.
