Supermodel Heidi Klum is no stranger to posting sizzling shots on social media, and this cleavage-baring pic is no different. The 39-year-old stunner tweeted on December 20, “Thank you for another beautiful day!” When it comes to keeping her bodacious bod magazine-ready no matter what the season, Klum is devoted to yoga, boxing, and running. To lose her pregnancy weight, she went to celebrity trainer David Kirsch and sweat up a storm with core exercises, lunges, squats, and shadow boxing.
