Singer Miranda Lambert will be going head-to-head with her husband Blake Shelton on his U.S. talent show The Voice next year (14) after signing on to serve as a mentor for his rival judge Shakira.
The House That Built Me hitmaker recently headed to the Los Angeles set of the reality program to shoot episodes for season six - but it wasn't Shelton the competitive star chose to lend her expertise to.
A source tells Us Weekly magazine, "Shakira and Miranda got along well. Blake joked that Miranda was helping another coach. But it was in good fun."
Shakira and R&B hunk Usher served as replacements for Christina Aguilera and Cee Lo Green during season four, when the original judges decided to take a break from the show, and the newcomers will return for another run in 2014.
Guest mentors for the current fifth season of The Voice are Ryan Tedder, Miguel, Ed Sheeran and superstar Cher.
