Playboy king Hugh Hefner made sure Anna Faris measured up for her role in THE HOUSE BUNNY - by ogling her breasts.
The actress researched her part in the film - in which she plays an outcast Playboy bunny - by wandering around Hefner's famous mansion in Holmby Hills, California.
And she insists Hefner lived up to his reputation - by checking out her figure every chance he got.
The Lost in Translation actress says, "Hef just stared at my chest."
Faris believes the famously wild parties Hefner throws at his mansion could soon become a thing of the past, because the House Bunny cast are planning to hold their own upcoming bash there.
She says, "It's gonna be so great that it will be the final party. After this one, maybe he just won't be able to (stage any more)."
