OMG!! This is so heartbreaking! Channing Tatum and Jenna Dewan-Tatum jointly announced their separation through instagram, breaking the internet and the hearts of fans worldwide. Channing and Jenna met on the set of the movie "Magic Mike." Not sure if you know this, but Jenna actually choreographed and taught Channing the dance he does to "Pony" in the movie. I personally think she looks more sexy doing it too! I posted the video from Lip Sync Battle below!
