The-dream - The-dream Made Millions From Rihanna
The-Dream made $15 million from writing Rihanna's breakthrough hit 'Umbrella'.
The producer claims he typically commands a high percentage of royalties for the tracks he writes but the Rihanna track - which was a number one single in fifteen countries - is one of his biggest payouts.
He told BBC Radio1 DJ Tim Westwood: "That one, I'd say was maybe about 15 million."
However, not all of The-Dream's hits have led to him to big paycheques, as when he made Justin Bieber's biggest hit, 'Baby', he only asked the record company to pay for his hotel room.
He added: "I said to the Def Jam A&R, 'Okay. You pay for my hotel room - I was in New York and I stay at the Plaza - and I'll write you a record.'
"And he said, 'No, we're not going to pay for your hotel room,' and I said, 'Okay, well I'm not gonna write you a record.' So, I guess everybody thought about it, then they were like, 'O.K., Let's pay for it.'"
