Reba, Blake Shelton Sing With Kelly Clarkson at L.A. Tour Stop

Kelly Clarkson welcomed several special guests to the stage at her 2012 Stronger tour stop at Los Angeles' Nokia Theater last night (April 3). Among them were country singers Reba McEntire and Blake Shelton, for separate performances. (Watch both below.)

'The Voice' coach filled in for Jason Aldean on the duet 'Don't You Wanna Stay,' which picked up both the Single and Vocal Event of the Year honors at the Academy of Country Music Awards on Sunday (April 1). As Kelly welcomed the "phenomenal country singer," she told the crowd, "I love him. He is so freaking awesome. I love his music. I love his cursing. I love how he messes with people all the time, that makes me like him more."

During the performance, the pair were extremely playful, having lots of fun with singing a love song to one another. Neither was able to keep a straight face, especially when Blake "lovingly" ran his hand along Kelly's cheek.

Reba had it a bit easier, singing a song that she and Kelly took to the second spot on the country charts in 2007. The pair performed their rendition of 'Because of You' -- which was originally a Top 10 pop hit for the 'American Idol' winner by herself -- to deafening cheers.

Other collaborations with the 'Mr. Know It All' singer Tuesday night included Michelle Branch, singing The Wreckers' hit 'Leave the Pieces' with the headliner. Kelly also brought out a finalist from her season of 'American Idol,' Tamyra Gray, to sing the Mariah Carey and Whitney Houston duet, 'When You Believe.'
