(BANG) -Ashley Olsen is unlikely to ever act again.

The 25-year-old star - who made her acting debut aged just nine months alongside her twin Mary-Kate in 'Full House' - hasn't appeared in a film since 2004's 'New York Minute' and has no plans to return in front of the camera.

She said: ''We worked non-stop until we were 18. Then we decided to take a break and go to school - and that was when we decided to question whether we would carry on in entertainment.

''It was time to step behind the process. I wanted to work on other things.

''It doesn't mean I'm not interested in Hollywood, I like the way it operates and the people who are involved and the sense of possibility. But if I ever do get back in, it's not going to be as an actress.''

Though Mary-Kate has made some film and TV appearances since 'New York minute' - including an eight-episode stint in 'Weeds' - she also thinks it ''felt right'' to step away from acting.

She said: ''It just felt right to move away.''

The pair now run a fashion empire and though their Dualstar Entertainment Group has over 30 full time staff, Mary-Kate and Ashley insist on being very hands-on with all of their business ventures.

Ashley told the new issue of Britain's Elle magazine: ''We don't trust a lot of people. We are perfectionists. We've always wanted to be closely involved with everything, totally hands on - that's why it works. If we step away, it stops working.''

Mary-Kate added: ''I know it sounds controlling, but that's how it has to be. It is a big responsibility - but we've been doing it for years.''
