Actress Sharon Stone and her toy boy lover Martin Mica have split, according to U.S. reports.

The 54 year old started dating Mica, 27, last year (12), but insiders tell Life & Style magazine the couple broke up earlier this month (Jan13).

A source tells the publication, "She called it off just after the holidays... They didn't share the same interests.

"Sharon is so busy. She has three sons and that keeps her hands full and (she) still travels a lot for work."
