Cee Lo Green has admitted he is attracted to Rihanna because she is "aggressive and sexually liberated".
The 'Forget You' hitmaker, who joined Madonna on stage for her Super Bowl Halftime show at the weekend, said her racy behaviour is also the reason she has a large lesbian following.
Speaking to Esquire, he said: "I was touring with Rihanna, and I didn't realise that she has a very particular following. You know what I'm saying?
"Let me be specific. Rihanna has a large lesbian community that comes out to see her shows. 'Cause she does a lot of girl-on-girl kind of stuff."
He added: "It's very racy and sexually charged. And I like that. I like aggressive and sexually liberated women. It's hot to me."
The singer, who is currently working on the second season of US talent show The Voice, released his latest single 'Anyway' before Christmas.
