Grammy-winning country singer Miranda Lambert will perform with finalist Dia Frampton on the live finale of 'The Voice,' NBC confirmed Friday.

"Miranda is an amazing artist and it will be fascinating to see her blend her talents with those of Dia,” said Paul Telegdy, Executive Vice President, Alternative Programming, NBC and Universal Media Studios. “This special duet is what 'The Voice' represents to our audience. Together, Miranda and Blake, who represent a true power couple in country music, will help provide a memorable finale for our first season."

That Blake he was referring to is, of course, Blake Shelton, Lambert's husband of just over one month. Shelton is one of four judges on the show, alongside Christina Aguilera, Cee Lo Green and Adam Levine.

No word yet on what Lambert and Frampton will sing together.

The finale of 'The Voice' airs Wed., Jun. 29 at 8PM ET.
