Mariah Carey came in on the show this morning and proved she wasn't a huge diva - she denied that she demands red carpets and candles when she arrives at a hotel, which was frankly disappointing. She also used the Radio 1 toilet even after Chappers had been in there with his upset tummy!
And Mariah also agreed to be the first person to have the Radio 1 Star Phone
Here's how it works:
We give a celebrity our Radio 1 Star Phone
They agree they'll answer it whenever we call them up
They must pass it on to the next celebrity they meet
We'll keep calling up the phone this week - it could be Mariah, it could be Snoop or Jay-Z who answers. Stay listening to find out.
