"Was I in love with Johnny?" The actors behind beloved 1989 teen movie Say Anything and characters Diane Court and Lloyd Dobler shared a romance off-screen, too, but it happened years later, actress Ione Skye writes in her new memoir.

Elsewhere in the memoir, Skye, who began acting at age 16, dished on her short-lived fling with fellow co-star, Matthew Perry, with whom she starred in 1988's A Night in the Life of Jimmy Reardon, alongside River Phoenix. While she originally had a crush on Phoenix, it was her and Perry who would end up getting together years later.

The actress talks to PEOPLE about why she decided to tell her life story — including having an abortion with Anthony Kiedis and why her marriage to Beastie Boy Adam Horowitz fell apart — in her memoir 'Say Everything.

Ione Skye shared she was intimate with ‘Say Anything’ costar John Cusack years after the film hit theaters in 1989
