Lady Gaga is being sued by music producer Teddy Riley as he claims he hasn't received any royalties for her 2009 track 'Teeth'.
Riley, who was a member of nineties hip hop group Blackstreet, believes he is owed 25 per cent of the writing fees and is now seeking $500,000 according to TMZ.
The 46-year-old has filed the lawsuit against Gaga for the song which was included on her huge Fame Monster EP which also include 'Telephone', 'Bad Romance' and 'Alejandro'.
The former Blackstreet star is no stranger to filing lawsuits as he has even attempted to sue his own daughter, Taja, after she claimed she had co-written 'Teeth'.
