Listen to One Direction on iHeartRadio

One Direction stars Louis Tomlinson and Harry Styles can't bear to be separated from each other - but that doesn't mean they're lovers.

The two guys are close enough that the gay rumors started swirling months ago, and they're starting to wear thin for Tomlinson. He tells MTV, "This is a subject that was funny at first, but now is actually hard to deal with, as I am in a relationship. Me and Harry are best friends. People look into our every move - it is actually affecting the way me and Harry are in public. We want to joke around, but there seems to be a different rumor every time we do anything."
