Twilight actress Nikki Reed is sinking her teeth into a new line of work - as a music video director.

The 21-year-old star, who plays bloodsucker Rosalie Hale in the vampire film franchise, fears she'll struggle to land acting jobs when her work on the series ends.

So she's diversifying in a bid to increase her job options.

Reed explains, "I don't think I'm going to be an actor forever. Unfortunately, with time and age your career slows down. It's just a fact. But I'm directing for the first time in a week... I'm directing a little music video for a friend of mine who's a wonderful musician, her name is Sage."
