President Bush's daughter Jenna Bush raunchy dance moves at a New York nightclub might have earned her criticism, but Hillary Duff seems to be defending her.

According to Star magazine, Bush was celebrating a friend's bachelorette party when shots were taken of her showing off her thong.

"I went to camp and Jenna Bush was a camp counsellor at my camp. She is such a nice girl. You just look at her and (see) she's nice. I think that she gets it 10 times harder than every other (23-year-old) girl out there, 'cause her dad's the president. She should be able to have fun and do what she wants and not have people antagonising her," Duff was quoted as saying.
