There was one person who believed Sharon Stone would be a star even when her father didn't -- Muhammad Ali. The Golden Globe winner dished to ET on Saturday about meeting the late boxing legend when she was a teen, and how he inspired her.

"I met him when I was 17," Stone told ET at the Hotbed Gala benefiting her charity, Planet Hope. "I was in the Miss Pennsylvania pageant and he was in Hershey, Pennsylvania, when I was there and I met him. And then he called my father and offered me a part in his film that he was making."

While Ali saw Hollywood potential in the young Pennsylvania native, Stone's dad thought otherwise.

"My father said, 'She is not going to be in film,'" Stone recalled. "He told my father, 'You may think that she is not, but she is. You cannot hide that girl under a bushel basket. Her light is too bright.'"

In 2012, Stone reunited with the champ at his charity event, Muhammad Ali's Celebrity Fight Night XIII, where he proved his memory might have been as good as his footwork.

"I said to him, 'I met you when I was a teenage girl and you might not remember that,'" she recalled. "I was helping him up the stairs because of his Parkinson's and he turned to me and he said, 'Yes, and you were wearing a blue dress.'"

Ali and Stone bonded over their shared passion for giving back, which Stone continues to do, helping raise $330,000 over the weekend by hosting the Hotbed event.

"I think life is a service job and anybody who thinks they're self-employed isn't," she said.

When she's not looking for ways to help people, Stone is looking for someone to share her life with. The 58-year-old actress is on the market and in the dating scene, but she's taking things slowly.

"I don't want to take the time out to just go on a date or have sex with a stranger," she said. "I don't want to just be with someone to be with them ... When it happens, I'll be with it."

The Late Late Show host James Corden caught wind of Stone's search for love last month and had some fun with her in a rap video meant to score her a quality date.

In the song, titled "I'm Sharon Stone, B**ch," Corden lists some of Stone's amazing traits.

"None of her instincts are basic / b**ches better bow down / She'll make you forget your whole life / Total Recall," he raps.

"He came up with this and I said, 'I'll do it as long as I can have a grill,' and they said OK," Stone explained. "I went to the studio and we did it in 45 minutes. It was like boom boom!"
