Taylor Swift Taylor Lautner

Actor Taylor Lautner is heating up the big screen in 'The Twilight Saga: New Moon,' with his role as 'Jacob' -- a werewolf. But the 17-year-old is staying sheepish when it comes to his rumored romance with Taylor Swift.

In a cover story for the latest issue of Rolling Stone, Lautner says he and 19-year-old Taylor, "instantly clicked" while working together on the upcoming comedy film, 'Valentine's Day.'

"Aside from being beautiful, she's extremely funny, charismatic and fun to be around," Lautner says of the singer-songwriter.

For her part, Taylor Swift continues to stay mum on the whole 'are they or are they not dating' question. Not surprising since, when discussing relationships with the members of Gloriana, the entertainer was quoted as saying, "You've got to keep the mystery."
