A new cute couple alert could be on the horizon after reports have surfaced, linking Twilight's Taylor Lautner to his Valentine's Day cast mate, Emma Roberts.

The pair met whilst filming the all star ensemble film in the autumn, but at the time Taylor was dating his namesake, Taylor Swift.

But now the 18-year-old could be getting sweet on Julia Roberts' niece, Emma after the two were spotted getting close at Vanity Fair's post Oscars party.

A source told OK! that Emma is keen on Taylor: “She thinks he’s the cutest thing ever.

“They met on the set, and there was an instant attraction.”

A witness saw the pair together at the Vanity Fair party on March 7 and said: “his arm was around her waist and she leaned her head on his shoulder. They talked for 40 minutes, with her hand on his knee!”

Ooo! We hope the pair will hook up! They'll rival Joe Jonas and Demi Lovato on the cuteness stakes...

Valentine's Day Los Angeles Premiere!
