One Direction's Louis Tomlinson: Harry Styles and I aren't in a gay relationship - I love Eleanor Calder
The 1D singers have such a strong bromance that some fans have started calling them 'Larry Stylinson'.
But Louis insists he's not homosexual and says he's totally loved-up with University Of Manchester student Eleanor Calder, 20.
'I'm a one-woman man with Eleanor,' he says. 'I'm a very loyal boyfriend.'
Louis, 20, admits the gay rumours have made things awkward for him and Harry, 18.
'This is a subject that was funny at first but now is actually hard to deal with as I am in relationship,' he tells Tumblr's Storyboard.
'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 rumour every time we do anything. I act the same way with Harry as I do any of the other boys.'
Harry has been single since splitting from Caroline Flack in January.
