"Funnyman" Jonah Hill has sparked rumors he's dating Lisa Marie Presley's model daughter Riley Keough, after the pair was spotted getting close during a night out in London.

The SuperBad star's love life has been given a boost since his recent rise to fame.

Hill, 25, entertained 20-year-old Keough throughout the night after they arrived together at London nightclub Boujis last month.

And new pictures of the pair leaving hand-in-hand at the end of the night have prompted rumors they're an item.

A source tells Star magazine, "Jonah and Riley partied side by side all night. She had her hand on his leg and was whispering in his ear... (She was) laughing at every word he said."
