John Legend [1] hosted ABC's A Bigger Love Father's Day [2] special on Sunday night, and there were no shortage of cute family moments. In addition to making us laugh with some all-too-relatable skits about parenting, the talented singer put on a few stellar performances. One highlight was when he performed "I Do" from his new album Bigger Love in front of his wife, Chrissy Teigen, and their two children, Luna and Miles. As Legend crooned the lyrics to the song, his mini-mes [3] could be seen dancing along to the beat. As if they couldn't be any cuter, they ended the performance by sharing a heartfelt hug. Aww! Watch the adorable performance above.
