The actress doesn't want to reveal how she and Johnny spend their time

Johnny Depp‘s girlfriend Amber Heard is keeping quiet on their blossoming romance.

The actress, 27, often spends time on Johnny‘s private Caribbean island but refuses to say what they get up to there.

‘The island… is my private life,’ says Amber.

Amber and Johnny, 50, met on the set of The Rum Diary in 2011 and got together after he split from long-term love Vanessa Paradis last year.

Despite dating one of the world’s biggest stars, bisexual Amber wants to be taken seriously in her own right.

‘I have something more to offer than the superficial stuff,’ Amber tells Bullett magazine.

‘When my agents go through the initial filtering process, I’ve asked them to always put scripts that don’t have the description of the character as “beautiful”, “sexy” or “hot” at the top of the pile.’
