One Direction have been invited to attend a party at the White House by Michelle Obama, a spokesperson for the President's wife has confirmed.

The boy band were introduced to the first lady backstage at this weekend's Nickelodeon Kids' Choice awards in LA.

They can't attend the annual event, which includes an Easter egg hunt, as they'll be on tour in Australia.

In March they became the first British group to go straight to the top of the US music charts with their debut album.

The group - put together on the UK X Factor in 2010 - shifted 176,000 copies of Up All Night, which only went to number two in the UK charts in December 2011.

One Direction are returning to the US and Canada in the summer to tour.

It was recently announced that Olly Murs will support them at some of those gigs.

To hear the full story of One Direction in America, with access to the band across five whole days of their US tour, listen to Radio 1 Stories on Monday 2nd April at 9pm. Or on iPlayer for 7 days after that.
