Sylvester Stallone is in hell -- but in a good way! The 70-year-old actor is the father of three gorgeous daughters -- Sophia, 20, Sistine, 18, and Scarlet, 14 -- who accompanied him to the Guardians of the Galaxy Vol. 2 premiere on Wednesday night.

“All I know is God must hate me to give me these daughters. They’re making my life hell, but in a good way,” Stallone quipped to ET’s Cameron Mathison on the red carpet. “Is there such a thing as good hell? Because that’s where it’s at, it’s great, they’re amazing.”

The gorgeous girls admitted to stealing actor Liam Hemsworth’s phone number out of their dad’s phone in a recent interview with Harper’s Bazaar.

“Can you believe that?” Stallone said to ET. “How about they dialed it. Thank god he didn’t pick up!”

In the new Marvel film, Stallone makes a brief cameo as the highly anticipated superhero Starhawk.

“I needed somebody who had intensity and power to do that and I don’t think it’s anyone other than Sly that can do it,” director James Gunn told ET.
