With a face as sunny as the creamy blonde hair atop it, teen dream Hayden Panettiere is the very definition of “pert,” so it’s no surprise that she was a shoo-in to play perky cheerleader Claire on the hit TV series Heroes. But there’s been no rah rah, sis boob bah-baring as yet; unfortunately we’ve only seen Hayden laden with clothes. This luscious little lass is barely out of her high school years, though, and there’s plenty of time for the former soap star to get dirty. When will we see Panettiere without her panetties? Soon, judging by her all-grown-up, sizzling turn in the cleavagefest The Architect (2006). Though Hayden bragged to the press about her "nude" scene in I Love You, Beth Cooper (2009), the only people who saw the petite pretty naked were the cast and camera crew—and even they probably saw nothing nipple patches. All that made it to the screen was a lot of bare back and the slightest sliver of side boob. Mr Skin does not love that, Beth Cooper.
