Ke$ha had a “diva moment” when she had her bed custom-made to ensure it was the “biggest in the world”.

The 25-year-old singer has been busy promoting her new album Warrior, which features Iggy Pop and The Flaming Lips’ Wayne Coyne.

When she gets the chance, the Tik Tok singer likes to relax on her super-size bed.

“I have a huge bed, like the size of this room!” she revealed to BBC Radio 1.

“It was my one diva moment. I said, ‘I want the biggest bed in the world!’ So I got the dimensions of the biggest bed – and made mine bigger. I can fit the whole of the Flaming Lips and some of my friends and my cousin and my cat comfortably!”

The American star recently released the first single, Die Young, from her second studio album.

Ke$ha is persistent when it comes to persuading artists such as Iggy Pop to collaborate with her.

“It was maybe the best experience of my life [working with Iggy Pop]!” she gushed.

“He is like the epitome of punk rock! No, he didn’t wear a shirt to the studio and I was so happy he was topless! I have been harassing him for years! I like to stalk people – it’s one of my hobbies. I like to weasel my way in there and this time it worked! I just bother people until they have to acknowledge my presence; I bother the hell out of them.”
