Penelope Cruz doesn't think she is beautiful.

The Spanish actress — who appears alongside Scarlett Johansson in Woody Allen?s new movie 'Vicky Cristina Barcelona' — insists despite being one of the world?s most famous sex symbols, she doesn?t think she is attractive.

She said: "I don't think I am beautiful. I can look good and I can look ugly. What's funny is that when I was younger I wanted everyone to look at me. Now I like to watch other people because you can learn a lot of interesting things."

Cruz — who is dating Oscar-winning actor Javier Bardem — also revealed she has no plans to marry the 'No Country For Old Men' star.

She added to Parade.com: "My family, my brother, my sister, they're always complaining that I'm too protective and I've always been like that. But I don't know if I believe in marriage. I believe in family, in love, in children."
