Former MTV UK host Emma Willis has been confirmed as the new presenter of Big Brother and Celebrity Big Brother on Channel 5.

The 37-year-old presenter, who is married to Busted star Matt Willis, is to replace Brian Dowling, who has been the main show's host since it moved to Channel 5 in 2011.

Speaking about the gig, Willis said: "I am thrilled to have been offered this job. I'm a fan first and foremost so to be able to front the show is going to be amazing. Roll on the summer!"

Meanwhile, Channel 5's Director of Programmes and former TV3 Director of Programmes Ben Frow said: "Emma is a natural on screen, she's made the spin-off show her own and now the time is totally right for her to step up. I know she'll take Big Brother to the next level and I can't wait to see her dealing with the housemates, both famous and soon-to-be famous.

"I'd also like to thank Brian Dowling for doing such a sterling job over the last two years. He's been a big part of the success of the show and I wish him the very best."

Big Brother and Celebrity Big Brother will return to Channel 5 in the summer.
