Warner Bros. Pictures has bought the film rights to Melissa de la Cruz's steamy young-adult book series The Au Pairs, setting up the first novel to be adapted and produced by Drew Barrymore's Flower Films, according to Variety.

Three books have been published in the The Au Pairs series, with the fourth due out next spring.

The first, The Au Pairs, takes up as three teenage girls learn how the other half lives when they take summer jobs as au pairs for a wealthy family with a home in the Hamptons.
