Actress Cameron Diaz finds it difficult to maintain a relationship - because she is "a spoiled brat."

The Charlie's Angels star has dated a string of Hollywood stars including Matt Dillon, Jared Leto and singer Justin Timberlake. And the star - who is now dating Jennifer Aniston's ex Paul Sculfor - claims her selfishness often hinders long-term romances.

She says, "It's really hard for me to commit. It's probably a lack of discipline on my part. Honestly, I'm just a spoiled brat who's used to getting my own way all the time! I'm sure that's what it is. I'm sure I'll suffer for it later, but I'm happy with it right now."
