Oliva Munn is recalling her steamy love scenes with Jon Hamm on their new show, Your Friends & Neighbors. In the new Apple TV+ series, the actress, 44, plays a character named Sam who is having a secret affair with 54-year-old Hamm's Andrew "Coop" Cooper — a former hedge fund manager who is "still grappling with his recent divorce." While attending the show's premiere in New York City on Tuesday, April 8, Munn, who wore a shimmering silver Roland Mouret dress, exclusively tells PEOPLE that "there's a lot of sex scenes" in the show and reveals that there was "a lot of dialogue" about getting them just right prior to filming.
