BBC radio presenter Scott Mills has remembered some of his favourite celebrity encounters from his time at Radio 1, as he prepares to move to Radio 2 in the autumn.
The DJ, whose final show on the station aired on Thursday (August 25) told Kate Thornton his 'top three' of celebs he had ever worked with were Katy Perry, Rihanna and Mariah Carey.
But after 24 years at the station he has a long list of celebrities he's worked with, who have played along with his 'Innuendo Bingo' game and remembers one prank which went particularly badly.
From his early days at the BBC, he remembered recording Top of the Pops at the broadcaster's Elstree studios and going into the canteen on his lunch break which he called 'a standard work canteen'.
He told Kate Thornton on White Wine Question Time: "The combination of people was so wild.
"I actually haven't thought about this for years, but this is bringing the flashbacks. Queuing up for food were Beyonce, Kelly, Michelle — Destiny's Child — and Barbara Windsor. Literally in the same queue and I'm like: 'What is my life?'"

Reeling off a list of stars who had joined in Innuendo Bingo, where they hold water in their mouths and try not to laugh, he said they included Daniel Radcliffe, Hugh Jackman and more.
But he called Jennifer Aniston 'one of the best' because she agreed to go along with a prank he had planned on friend and co-host Chris Stark.
He said the actor was one of the best people he'd ever met 'in terms of how famous they are versus how lovely they are' which was what made it all the more surprising for Stark when she turned on him in an interview.
He remembered seeing Stark's face 'drain' when she said she wouldn't answer the question, though she'd told Mills beforehand she didn't want to be 'that mean'.
"She didn't have to be that mean, because you could see his face just go like, whoa," Mills recalled. "And then I burst in and it's all fine. But just to be able to pull that off, with her help, was quite incredible."
But he also remembered a 'misjudged' prank he tried to pull on Katy Perry when she appeared on the show in a segment called 'You Control Katy Perry' where listeners could write in and tell her what to do.
Mills had booked a Russell Brand impersonator - at the time the pair were still married, though Mills admits "you don't know what's going on in someone's life, maybe they were having troubles or who knows".
He said he was surprised by how much the impersonator looked like Brand, since he didn't online, and that Perry really believed it was him.
"And then she ran off and cried," he said. "I was like, we have massively messed this up."
With half an hour of the broadcast still to go, Perry was refusing to go back out and take part again so Mills went to in to apologise.
He told her: "I'm so sorry, we've misjudged this so much.
"And she went: 'It's okay. You just better play my f*****g records forever."
And of one of those listed in his top three, singer Rihanna, Mills remembered she was never on time, and once even replied to him on Twitter during a show that she would 'be there soon'.
"The thing is really when she does arrive, she is incredible. So it was worth the wait," he said.
