Katharine McPhee – Celebrity Wardrobe Malfunctions

On the set of 'The House Bunny,' 'Smash' starlet Katharine McPhee showed off more than just her acting skills. The former 'American Idol' contestant had a Marilyn Monroe moment when her colorful dress went flying up due to a gust of wind.

This wardrobe malfunction might be one of the tamer mishaps on our list, but that doesn't mean the gorgeous McPhee didn't turn a little red in the face when her underwear and toned cheeks were on display for all to see. Her booty is super nice though, so she should be feeling more proud than abashed. Those workouts are definitely paying off!

On a side note, we bet Katy Perry's ex hubby, Russell Brand, is somewhere drooling over this picture right now...
