Tyra's in trouble.

Tyra Banks has been sued for $3 million by the mother of a teen sex addict, the Atlanta Journal-Constitution reports.

Angry mother Beverly McClendon charges that her daughter appeared on Tyra, the supermodel's now-defunct talk show, without her permission.

The 15-year-old girl in question reportedly answered an online casting call looking for teen sex addicts to talk about their problems on the air. Tyra producers later flew her from Georgia to New York and provided hotel lodgings -- all without McClendon's necessary consent -- the lawsuit claims.

In the suit, filed in federal court Oct. 8, McClendon frets that the episode "was undoubtedly watched by sexual deviants, perverts and pedophiles alike," and violated her daughter's privacy.

She'd also like to prevent future airings of the controversial episode.
