The actor, who appears in the vampire movies as the character Jacob Black, is playing down reports that they are an item.
The pair were spotted having dinner together in LA before going to watch a hockey match, putting the rumour mill into overdrive.
But when asked about it at a press conference for the new Twilight movie, New Moon, Lautner decided to remain coy and keep everyone guessing, telling US Weekly: “The very funny thing is that all of you have seen every single move I make, so I guess I can leave that up to you to decide.”
However, he did raise eyebrows when he hinted that the sexy singing star – who used to date Joe Jonas from the band the Jonas Brothers – might have written a song for him.
When asked if the country star had ever penned a tune for him, Lautner answered: “That’s a scary thing. I don’t know if she has. I have no idea.”
It’s just the latest rumoured romance that’s being linked to the cast of the popular movies, following all the hype surrounding Robert Pattinson and Kristen Stewarts possible relationship.
