Actress, comedian, talk show host and... super sleuth?

Ellen is doing her bit to get to the bottom of the Who Bit Beyonce? saga (yes, it's still going) and if that means wheedling info out of her guests on The Ellen Show, then so be it.

John Legend was on the show yesterday to discuss his recent Jesus Christ Superstar role, and talk soon turned to his and Chrissy Teigen's daughter, Luna - who, as he proudly declared, had just said her first 'Beyonce'.

Ellen used this as a segue into the WBB? drama and Legend admitted that he, along with Teigen, knew who had bitten her - and that it was a famous 'person' (not necessarily an actress).

It wasn't long before he shut the conversation down, but it's thrown up a whole new set of clues, particularly since prime suspect Sanaa Lathan is an actress.
