Hollywood A-list Star Sharon Stone has kissed tons of leading men on-screen, but when it comes to kissing, she said that Robert De Niro is better than all the rest.

Stone and De Niro starred alongside one another as husband and wife in the 1995 movie Casino. While appearing on “Watch What Happens Live” on Tuesday night, Stone was asked by a caller who her best and worst on-screen kissers were.

“Robert De Niro was for sure the best kisser,” declared Stone, 62. “Bob was far and away the best kisser.”

“He was the actor that I admired the most,” she added. “My whole career I just wanted to be able to sit across the table from Robert De Niro and hold my own. Maybe because I just held him in such extraordinary high regard, it was the pinnacle of the kissing moment for me.”

“I was just so madly in love with him as an actress to start with that he probably could’ve hit me in the head with a hammer and I would’ve been like, ‘Oh, yeah!’” Stone continued jokingly. “It was pretty fabulous.”

Stone went on to say that every on-screen kiss that she had after De Niro was “just meh.”

Stone made headlines earlier this month when she spoke out to say that physical looks really do matter.

“You don’t even realize how much [looks] matter until they start to go,” Stone told the Telegraph, adding that it’s a “big, fat stupid lie if anyone says that they don’t.”

The Basic Instinct star remains disciplined about maintaining her trimmed physique, despite the coronavirus pandemic. She said that her workout routine involves “30 squats a day, and lift[ing] these 7-pound lead balls when I’m watching TV, just because I can’t get to the gym these days,.”

In this new interview, Stone said she felt vindicated by the #MeToo movement after years of being labeled as “difficult” or “hard to work with.” She specifically remembered one director who “asked me to sit on his lap every day to receive direction.”

She also recalled a male actor in the cast of the 1984 film Irreconcilable Differences, who once yelled in reference to her on a crowded set, “‘Would you get out of the f—king way? I can’t even see her tits!”
