Talk about an epic couple comeback! Channing Tatum and Jessie J confirmed they are back together in the best way -- by making their red carpet debut! Just days after E! reported the "Magic Mike" actor and the "Bang Bang" singer had reunited after a month-long break, they walked arm and arm on the red carpet to support Aerosmith who was receiving Person Of The Year at the MusiCares event in Los Angeles on Friday. Their public union was also made hours after he finalized his divorce with Jenna Dewan.
