Listen to Miranda Lambert on iHeartRadio

Miranda Lambert will once again lend her talents to NBC's "The Voice."  But this time around she's not helping out husband Blake Shelton.  The country star is on board as an advisor to Shakira, who'll be filling the chair left vacant by Christina Aguilera. 

Miranda tells "Access Hollywood" she believes Blake is "kinda nervous about this whole situation," but adds it's good to "keep 'em on their toes."  Lambert also believes it's time for the show's female coach to win.  So far, singers from coach Adam Levine's team were the first and most recent winners, while Blake has coached three vocalists to victory. 

Also returning as a coach is Usher, who is once again filling in for Cee Lo Green.  "The Voice" will launch on NBC after the Winter Olympics, with the season six debut set for February 24th.
