Gloria Estefan at the New York Premiere of 'The Assassination of Jesse James by the Coward Robert Ford' at the Ziegfeld Theatre. New York City, USA - 18.09.07

The Miami, Florida-based singer discovered the hunky movie star was staying on celebrity hotspot Star Island, where she has a home - and she spent the weekend getting into shape.

She says, "I almost lost 10 pounds in a day because Denzel was staying on our island and I was running and jogging, waiting for him to come out... I just missed him."
