Michael Buble’s ties to country music keep growing!

The Canadian crooner has already collaborated with Blake Shelton on Blake’s mega hit remake of “Home,” and Michael has even joined Blake as his advisor on the current season of The Voice.

But who may be next to band with Buble?

Reese Witherspoon isn’t a real-life country singer, but she played one on the big screen in her Oscar-winning performance as June Carter Cash in 2005′s Walk the Line.

And Nashville native Reese has plans to sing next with Michael Buble. US Weekly reports the two are in talks to record a new song together.

Martina McBride has also been very vocal about vocalizing with the jazzy singer. Martina appeared on Anderson Live this week and revealed Michael is her dream duet partner.
