Claymates and Ruben Studdard fans unite! For the first time since their 'American Idol' debut in 2003, Clay Aiken and Ruben will tour together this summer, Clay told Chelsea Handler on 'Chelsea Lately' (weeknights, 11PM ET on E!).

"We're very, very, very different people -- besides the fact we look exactly alike," joked Clay.

But the respective pop and R&B singers have stayed friends ever since being finalists on season 2 of 'Idol' seven years ago. Though Clay was runner-up, it's good to see there are no hard feelings between the two.
