The 26-year-old Princess Diaries star said that she plans to take time out from acting and return to song writing until she can find a new direction for her Hollywood career.
She told Digital Spy, 'I've had fun doing romantic comedies but I just can't anymore.
'There's nothing fulfilling creatively, there's nowhere to grow, nothing to learn from it, or for yourself. I'd rather just be home with my family or write music until that special project comes my way.'
Having got a taste for musical roles after voicing Rapunzel in Disney animation Tangled, she added that it is a path that she would like to explore more.
'It was fun to dip my toe in the water [in Tangled], but I'd like to do the real thing on the big screen. That'd be so much fun,' she said.
