In an attempt to bring some nostalgic Christmas cheer to The View, reality competition show relics Ruben Studdard and Clay Aiken joined forces to perform a duet of "This Christmas," while wearing matching red sweaters. Festive!

The former American Idol competitors also revealed it was the first time they took the stage together in 13 years. But for those of you concerned about the state of their friendship, worry not -- Aiken quickly declared the two remain close and keep in touch: “We FaceTime once every week or so, still."

Studdard echoed the "Invisible" singer's claims of closeness, saying, “[Clay] was one of the first people I actually met during Hollywood week and we’ve been friends ever since.”

And as for what Studdard's been up to in the years succeeding his 2003 American Idol win, he said, "I have been really blessed over the past 13 years to have released seven albums, I’ve been touring all over the world over the last 8 years doing the Hitman Tour with David Foster and just enjoying life. I’m actually producing a new children’s show right now called Uncle Ruben’s House."
