Blake Shelton isn't the only person in his marriage who is going to have all the fun on 'The Voice.' His wife, Miranda Lambert, who admitted her "jealousy" over the fact that her husband is a coach on the show and she isn't, will appear on the much-anticipated season finale this Wednesday, June 29. She'll be performing a duet with Dia Frampton, the finalist representing Shelton's team on the smash hit singing competition show.

According to AP, Lambert says, "It's been a joy watching my husband grow so attached to his team. Truthfully, I am a little jealous that I am not a coach myself. I can't wait to be a part of it." Shelton certainly adopted a father figure role to his team members on the show, which just might make Lambert the mother figure.

Be sure and tune in to your local NBC affiliate on Wednesday night at 8PM ET to watch Lambert partner up with Frampton, who is a favorite to take the competition.
