Sean Penn Caught With 24-Year-Old Girlfriend

Sean Penn hit the waves in Hawaii with 24-year-old actress Leila George! The National ENQUIRER caught the new couple got passionate in the water — with Sean's 23-year-old son Hopper along for the holiday!

Sean, 56, is just one year younger than Leila's father Vincent D'Onofrio, who found fame as Detective Robert Goren on "Law & Order: Criminal Intent." Sean's beautiful daughter Dylan is just a year older than Leila, as well.

Leila's mother is actress Greta Scacchi, and the aspiring actress debuted before the cameras in 2016 with James Franco's campy remake of the Lifetime Channel movie "Mother, May I Sleep with Danger?"

Sean — after briefly getting back together with his ex Madonna last year — has been working with Leila on an audiobook for a bizarre manuscript written by a mysterious author named Pappy Pariah.

Some publishing insiders are saying that Pappy is actually Sean himself — and it looks like Leila has gotten close enough to know the truth!
