Actress Emma Watson has become a certified yoga instructor.

The Harry Potter star, who graduates from Brown University with a degree in English in May (14), is hoping to get back to some of her favourite hobbies this summer, and that might find her taking charge of fans' yoga sessions.

Talking about life after university in the new issue of Wonderland magazine, the 23 year old says, "I feel like I have so much more to accomplish as an actress. I'd love to try theatre and that's a whole other thing.

"When I finish my degree, I will have a lot more time to pursue other passions, and I want to figure out what those will be.

"I love having something completely unrelated to the film industry. I want to find something that will let me use my brain in another way. I love painting, so maybe I (will) hone in on that and do more art classes? Or maybe something different. I'm a board two certified qualified yoga instructor."
