One Direction star Harry Styles made pop fans' hearts go wild yesterday (April 3) by meeting up with McFly and Busted's Matt Willis.

The 'Kiss You' singer was spotted with McFly's Dougie Poynter, Tom Fletcher and Danny Jones - as well as Willis - at the Loughran Gallery pop-up launch in London.

They formed something of a boyband supergroup as they posed for the camera in style.

Styles then partied away the night with Rita Ora at a birthday shindig for event planner Paul Rowe.

As previously reported, One Direction's Louis Tomlinson recently called on Busted to reunite and perform live.

The pop-rock group have been inactive since they split in 2005.
