Mariah Carey sues former assistant for 'blackmailing' her with 'embarrassing' videos

Mariah Carey is suing her former personal assistant, calling her an extortionist.

The pop superstar is accusing her former assistant of betrayal and blackmail.

The 48-year-old says Lianna Azarian secretly filmed her during personal activities and then threatened to release them if she didn't pay her $8 million.

Attorneys for Azarian say the lawsuit is only a distraction since she filed a wrongful termination lawsuit against the singer.
