When we saw them snogging at Glastonbury we assumed that Harry Potter star Emma Watson and rocker George Craig were, er, potty about one another...

But now the One Night Only frontman insists they are "just good friends".

As Emma was snapped returning from an all-girls' holiday in Thailand, right, we asked George what was going on. Catching him ahead of One Night Only's exclusive set for MTV Presents in Camden on August 19, he insisted: "We're just good friends, we've only ever been friends." Right.

He said they plan to crack America next year, as their "anthemic" sound "appeals more to the US market". Emma is at uni there. How convenient!
