Need something to smile about today? John Legend shared arguably the cutest video of him and Luna singing the "Baby Shark" song together on Instagram on March 26. The award-winning singer and father of two started off the adorable conversation with his daughter by asking her what was on his shirt. As soon as she answered "Daddy Shark" we saw where he was going. John immediately broke into song and 2-year-old Luna followed suit, busting out the chorus of the toddler anthem. And no, it seriously cannot get any cuter. Fingers crossed the dad comes out with his own remix!
