TLC returns with a surprise musical guest on the stage of the 2013 AMAs. Lil Mama joined TLC in a performance of their song "Waterfalls." Opening their performance with rain showering down around them, the group revealed themselves, dressed in all white. Lil Mama took on Left-Eye's part, but gave her own take on the verse ... not sure how I feel about her rendition, but it was a great throwback performance.
Watch it above!
