The couple, who co-star in the new movie 'Bobby,' sparked romance rumors when they attended a number of events together, but refused to confirm their relationship.

    But now 48-year-old Stone and her 37-year-old beau aren't hiding their affections for each other - they recently attended a party for fashion label Dolce & Gabbana at the Chateau Marmont Hotel in Los Angeles arm-in-arm and made sure everyone knew they were a couple.

    A source close to Stone says, "They're both really happy - but they don't have long-term expectations.

    "It's a fun fling for the holidays and Sharon is a good influence. She rarely drinks and has three kids. It's a good match for now."
