One Direction And JLS Perform Together On The X Factor

One Direction and JLS performed together for the first time on The X Factor yesterday night

The two former reality stars collaborate on stage at London's Wembley Arena.

The two bands, who both previously appeared on the series as contestants, sang a mash-up of their own hits at London's Wembley Arena.

JLS's Aston Merrygold, Marvin, Humes Oritse Williams and JB took to the stage first and launched into a rendition of their song, 'She Makes Me Wanna'.

Harry Styles, Liam Payne, Louis Tomlinson, Zayn Malik and Niall Horan then descended from roof of the venue to perform 'What Makes You Beautiful'.

The two groups then came together and ran into the middle of 10,000-strong crowd to sing the two tracks as one.

One Direction and JLS' collaboration came after the opening performances from this year's The X Factor finalists, Amelia Lily, Little Mix and Marcus Collins.

The X Factor final continues on ITV 1 tonight, with two acts going through to the second part of The X Factor final on Sunday (11^th December).
