Tiffany Haddish is riding high on success, but like all of us, she has had her share of troubles, heartaches and sorrows on the road to greatness.

In her new memoir, The Last Black Unicorn, Haddish gets real about her tumultuous childhood, including being raised by an abusive mother with schizophrenia and later being thrown into foster care, where she was molested at the age of 13 without even knowing it.

In the excerpt obtained by E!, the Girls Trip star claims that as a teenager she was bullied and abused while in foster care. In fact, the live-in father of one of her foster mothers offered to suck on her breasts to help them grow after he caught her stuffing toilet paper in her training bra at the age of 13.

The future comedian began letting the man do it every day for 15 minutes before she left for school. Years later, a 19-year-old Haddish told a friend about it, thinking that it was truly done to make her breasts grow. The friend then informed her she was molested.

“In my mind, ‘molested’ meant somebody hurt you in some kind of way,” she wrote. “Like, they took something from you that you didn’t want to give. And what the old man did never hurt. It didn’t necessarily feel good, either, it was just whatever. And he never tried nothing else with me, not even once. It was just like—in my mind—he was helping me out.”
