Just because Beyonce is real close with Coldplay's lead singer Chris Martin and his wife Gwyneth Paltrow doesn't mean that they'll work together.
It has been revealed that Beyonce turned down an opportunity to work with the group. Lead singer Chris Martin revealed it in a recent interview, along with the fact that Rihanna didn't turn him down:
"Well, I did write a song for Beyonce, but it got rejected by her A&R people. And the one I wrote for Rihanna didn't get rejected," Martin revealed to Maxim magazine.
He continued how his collaboration with Riri is his favorite on the Mylo Xyloto album. "She's f**king rad, and I love listening to her. It's my favourite real singing on the album, because it isn't me."
