The Summertime Ball 2012 star posts the personal footage online following his performance at Wembley Stadium.

Justin Bieber has released a new video which shows him singing his smash hit single 'Boyfriend' with his sister on a plane.

The 'One Time' star was in the UK this weekend to perform a triumphant set at Capital FM's Summertime Ball – where he was also joined by secret guest Carly Rae Jeosen – and posted the new footage onto his official Viddy account yesterday (10^th June).

His sibling Jazymn begins singing the tracks hook alongside the star before turning her head away from the camera in the adorable clip.

During one of his hometown gigs over the festive period in 2011, the Canadain star was also joined by his sister on stage as the pair performed 'Baby' during the acoustic set in Toronto's Massey Hall.

Meanwhile, the singer continues to perform secret shows around the world as part of a new min-documentary in promotion of his new album 'Believe' which will be released on 18th June.
