Sharon Stone breaks up with 27-year-old boyfriend Martin Mica

Sharon Stone and boyfriend Martin Mica's relationship lasted eight months, but the couple split just after the holidays.

That's according to a report from an anonymous source in Life & Style that claims the 54-year-old actress wasn't concerned about the age difference with the 27-year-old Mica: "They didn't share the same interests. Her passions are philanthropy, politics, activism -- he wasn't into any of that."

Stone also has a busy personal and professional life. She has three adopted sons and, according to IMDb, has seven movies in various stages of production or due for release including the recent Sundance Film Festival premiere "Lovelace," in which she plays porn star Linda Lovelace's conservative mother.
