Taylor Swift wants to move up in the world after her romance with diminutive Twilight star Taylor Lautner - she's looking for a "tall and funny" boyfriend.

The stars began dating after they were cast together in new movie Valentine's Day, but the romance fizzled out in December.

Sources blamed the split on a lack of "chemistry" but Swift, who stands tall at five foot eleven inches, hints a height difference was behind the break-up with Lautner, who is five foot six.

The Grammy winner tells OK!, "The bad thing about being tall is the majority of people are at a different eye level than you, and so you feel like you're looking down to talk to people, which is kind of unnatural - looking down to talk to people, and they have to look way up to talk to you.

"It just depends on what group of people you're around. If there are a few scattered tall people in the room or in the group of people that you're talking to, it's not awkward at all. But if you're around a bunch of little, mini-people and you're the only giant in the circle, it can be kind of interesting."

Swift also demands her next suitor can make her laugh: "Somebody who has a compatible sense of humour with me, that would be the most important thing."
