A former 'America's Next Top Model' contestant is suing Tyra Banks for $3 million, saying she was improperly denied a top prize because she used to be an escort.

City News Service says Angelea Preston filed the breach-of-contract suit Wednesday in Los Angeles Superior Court.

It names Banks, who is the show's executive producer, and The CW network.

The lawsuit says Preston won the show's Cycle 17 in 2011 and was entitled to a package that included a $100,000 contract with CoverGirl cosmetics and a magazine fashion spread.

Preston earlier appeared in the show's Cycle 14 in 2010. Cycle 17 was an 'All Stars Season' made up of former contestants.

Preston says she was wrongly disqualified because she had worked as an escort before taking part in the show.

'As noted during the broadcast of the "America's Next Top Model" finale in 2011, information about Angelea was learned after production wrapped on that cycle that led to her disqualification from the competition,' the CW said in a statement to The Wrap. 'We are confident that her lawsuit has no merit.'

Messages to an attorney and a manager for Banks from the Associated Press weren't immediately returned.

The CW did not immediately return a request for comment from MailOnline.
