Sharon Stone is now a single lady. That's right, the 54-year-old actress has split with Argentinian model Martin Mica -- you know, the much younger, handsome boyfriend whom she was photographed intimately making out with on beaches and at fashion shows over the summer. Stone and Mica, 27, allegedly began dating in May, after meeting at a Vogue Brazil party in Sao Paolo.

According to Life & Style magazine, the breakup doesn't have so much to do with age, but with values. "She called it off just after the holidays," a source told the publication. "It wasn't so much the age difference. They didn't share the same interests. Her passions are philanthropy, politics, activism -- he wasn't into any of that."

What's more, Stone is just too busy, okay? The source added: "Sharon is busy. She has three sons and that keeps her hands full and still travels a lot for work."

Stone isn't the only celebrity to have dated a much younger partner, of course. Flip through other May-December relationships in Hollywood in our gallery below.
