Oprah had better watch her back. Tyra Banks has just signed a multi-year deal with Warner Bros. that will have the model-host-producer developing scripted and reality shows for the studio as well as working on direct-to-DVD film projects. The America's Next Top Model host-producer will also do a series development deal with the CW and will continue hosting her syndicated talk show. The studio called Tyra "one of television's most versatile talents" while she returned the compliment with "Warner Bros. understands my brand and the reach and demand of our audience." The only question is: When will Tyra find time to sleep?!
