It's been over 13 years since RUBEN STUDDARD battled it out on "American Idol" against CLAY AIKEN (Ruben won the second season). The dynamic duo reunited on "The View" for their FIRST TV duet since then. They did a holiday favorite "This Christmas." Ruben said, quote, "He was one of the first people I met during Hollywood Week, and we've been friends ever since." And Clay said, quote, "We FaceTime once every week or so, still."
