Former X Factor star Olly Murs and TV presenter Caroline Flack have been confirmed as the hosts of this year's Xtra Factor.

The show is broadcast on ITV2 after The X Factor with behind the scenes footage and interviews with contestants.

The news was confirmed on the official X Factor Twitter feed late last night.

On the social networking site, Olly Murs said: "I'm confirmed on Xtra Factor! Co-hosting it! Proper excited! Off for auditions in Birmingham! NOW!!"

Caroline Flack also tweeted the news: "Here in Birmingham! Met the lovely Kelly and Tulisa. Gonna be a exciting day tommorow..great to see dermot...bring on day 1.

Since finishing second on The X Factor in 2009, Olly Murs has released his self-titled debut album with lead single Please Don't Let Me Go making it to number one in the singles chart.

Caroline Flack, 31, hosted Gladiators and the I'm a Celebrity, Get Me out of Here! spin-off show Now from 2008 to 2010.

It had been previously reported that Radio 1 DJ and entertainment correspondent Matt Edmondson was taking over from former presenter Konnie Huq.

Matt Edmondson jokingly said on Twitter last night: "Got my bag packed, train tickets booked to Birmingham, copy of Simon's autobiography! Can't wait!... What's that you say? OLLY MURS?!??!?!"

The main X Factor show is still hosted by Dermot O'Leary with Louis Walsh, Gary Barlow, Kelly Rowland and N-Dubz singer Tulisa Contostavlos confirmed as this year's judges.

The first audition for this year's show is today in Birmingham.

It'll then visit Glasgow, Manchester, Cardiff, London and Liverpool.
