Emma Roberts says she and her father Eric Roberts and aunt Julia Roberts have ''too many teeth'' for their mouths.
Emma Roberts' "crooked" teeth give her "character".
The 20-year-old actress - who is the niece of Julia Roberts and daughter of Eric Roberts - blames her family genes for the trait but says she doesn't mind the imperfection because it makes her look more interesting.
She said: "I have really crooked teeth - they give me character! We Robertses have too many teeth for our mouths."
The 'Scream 4' star also revealed she was inspired to become an actress by her famous aunt and actor father and admits spending so much time on film sets as a child was wonderful.
She told Women's Health magazine: "I grew up around sets . I would visit my aunt all the time and I just loved it. I was fascinated by the whole thing. You'd have to drag me off the set every time I was there!"
Last year, the pretty blond admitted she finds it "frustrating" that people think she is only successful because her dad and aunt are Hollywood stars.
She explained: "Sometimes it's frustrating because people think I'm only working or doing stuff because of my family when that's not true at all.
"We actually try to keep work life and family life completely separate, so it's just frustrating when I hear that because I've worked really hard.
"But I just have to fight for myself, fight to be accepted in a way and make my own name for myself."
