Supermodel Gisele Bundchen has recorded a version of the Blondie song “Heart of Glass” and is making it available on iTunes to benefit UNICEF. Why? Because nothing says “humanitarian aid to children and mothers in developing countries” quite like a beautiful Brazilian woman wearing a bikini. Oh, we forgot to mention that Bundchen also shot a video to accompany the song, and in it she’s wearing the teeniest tiniest animal-print bathing suit. (The song/video are in addition to a new, omnipresent ad campaign Bundchen is doing for H&M.) Meanwhile, the supermodel and her spouse, Patriots QB Tom Brady, were out and about on Marathon Monday, cheering runners along the race route. (Several people tweeted pictures of the pretty pair and their children Ben and Vivian.) Brady’s sister Nancy was among the 36,000 runners.
