Little Mix are celebrating after reaching a big Vevo milestone.

The group have now bypassed one billion views on the video streaming service.

The band wrote on Twitter on Monday (April 25): The girls have hit 1 BILLION views on @Vevo_UK.

"Use #LittleMix1Billion to let us know your fave LM vid!"

A number of fans responded by stating their favourite video, with the likes of 'Black Magic' and 'Hair' proving popular.

'Black Magic' incidentally is Little Mix's most viewed clip on their Vevo YouTube account with over 168 million hits, despite only being released last year.

The tune features on the group's third album 'Get Weird'.
