"I had a fur coat on, so when I took the coat off, the coat was heavy, and the strap came out with the coat. They were like, 'Tara, let me see the dress, let me see the dress.' ... I didn't see the strap fall down, so I'm smiling like an idiot. ... Then, when someone came up to me, I was like, 'Oh, I'm so embarrassed!'"

The 29-year-old actress said she was upset at the photographers' reaction to her wardrobe malfunction (search).

"I just hated that the paparazzi were high-fiving each other and laughing," she said. "It was so cruel. But it happened and ... you move on."

Reid also said she doesn't understand why she's labeled a party girl.

"What's the worst I've ever done? Dance on a table? Like, get drunk and dance on a table, what's so bad about that?"

Reid added that now that she's getting older, she's "calming down a lot."
