Photos of Nicole Richie at the Hard Rock Hotel in Las Vegas

Nicole Richie caused a bit of a stir over the weekend when she supposedly had to be escorted out of the Vegas Hard Rock hotel by security after getting into an altercation with another girl. We can't say that we were totally surprised given Nicole's former track record, but she definitely has put away her party lifestyle since Joel and Harlow came along. What do you think — is Nicole still a bad girl at heart?
