Coldplay frontman Chris Martin hopes to work with Rihanna again after teaming up with the 'Umbrella' hitmaker for her next album recently.
Martin said he composed new music for Rihanna's next album but he is not sure whether she has kept it.
"I wasn't necessarily with (Rihanna in the studio), I was working for her. I don't think she even asked, I just said, 'please can I try something?'," Martin said in a radio interview.
"She has so many amazing people writing for her. It's like trying to win 'American Idol', getting a song on Rihanna's album. It's hard. Everybody wants to write songs for her," Martin said.
Martin previously collaborated with Rihanna for 'Princess of China' off Coldplay's 2011's 'Mylo Xyloto' album.
