Rita Ora is to host 'America's Next Top Model'.

A source told The Sun newspaper: "Rita is in a dream world as she's landed the ultimate gig. She'll be mixing her two passions of fashion and music and taking over from a TV institution in Tyra.

"'Next Top Model' bosses wanted to inject some freshness back into the format and they see Rita as the ideal new face. She is releasing a new single later this year to coincide with it."

'America's Next Top Model' ran for 22 series over the space of 12 years before the CW Network pulled it last year.

But it has been picked up again by VH1 and former host Tyra will remain as an ex ecutive producer.

The 42-year-old-beauty was responsible for finding her successor and earlier this year spoke of her excitement about doing it.

She said: "I'm pumped to identify that person and bring back the show.

"'Top Model' fans, you demanded that the show come back and VH1 answered the call. Get ready for a fierce-a-fied rebirth!"

In the series a number of aspiring models compete for the title of 'America's Next Top Model', with the winner being given providing them with an opportunity to begin their career.

Rita's news comes the day after she was hospitalised for exhaustion.

The 'Body on Me' hitmaker took to Instagram to reveal she was being treated with an IV drip and getting some rest after a "tough" day.

And sources claim she checked herself into hospital after "working and partying too much".

One told the Daily Mirror newspaper: "She's completely exhausted, she hasn't had a break in months. She has been working solidly for the past few months then she parties whenever she gets the chance. She works hard and plays hard."
