A daughter of Hollywood tough guy icon Sylvester Stallone says she was once forced to run for her life in Manhattan to escape a deranged bicyclist who randomly accosted her.

Sistine Stallone, a 26-year-old model, opened up about her harrowing crime horror on the “Unwaxed” podcast this week and said she prays her ordeal will serve as a warning to other women walking the streets of New York City.

“There was this guy on a bike who just started yelling really inappropriate curse words at me,” the “Rocky” star’s daughter said. “He came up behind me on his bike and put his hands on me and that's when I freaked out and then he started yelling at me.

“I just start sprinting and going as fast as I can,” she said. “And he cuts through the crowd on his bike. Three blocks later I'm still running for my life and I come across the Sephora.

“I hide behind a makeup counter and think I've lost him. I see he's in the store screaming at the top of his lungs, 'You can't hide from me, b—h!' I'll find you, I'll get you!' “

Sistine said she crouched “in a bug formation” in the back of the store for about 15 minutes and thought to herself, “If he comes back here, I'm screwed.”

She said five employees tried to lock up the creep until the police showed up.

The Hollywood scion says her horrific ordeal should serve as a cautionary tale for other women in the city.

“I really hope this reaches all women because the saddest thing is that we see videos of New York girls every day – 'Oh, they were attacked on the West Side Highway, oh, they were groped on this street.'

“Don’t have headphones on or look down,” she warned.

It was not immediately clear when or where in Manhattan the alleged incident occurred.
