R&B hitmaker Teddy Riley is suing pop superstar Lady GaGa over allegations he has not been paid for his contributions to her song Teeth.

The Blackstreet star claims he was promised 25 per cent of the writing fees, but got nothing back for the 2009 track, which featured on her widely acclaimed album, The Fame Monster.

Riley is demanding $500,000 (£333,330) in compensation plus punitive damages, according to Tmz.com.
