Jennifer Nettles is relieved—her secret's out. Sugarland's female singer will serve as a judge in the upcoming musical competition Duets, which will debut on ABC this summer.

Jennifer seemed excited to finally be able to talk about the show to fans in a recent blog post on Sugarland's website. "Thank god, because I've been dying to tell you about it (it's hard for me to keep a fun secret!)," Jennifer writes.

Judges Jennifer, Kelly Clarkson, Lionel Richie and Robin Thicke will each hold auditions across the country to discover two amateur singers that will each serve as duet partners for the artist. The superstars and their trainees will perform each week, with the eventual winner taking home a record deal with Hollywood Records.

Onstage, Jennifer is a fearless performer, but she admitted to being nervous about the upcoming show. "This show will be a window into part of my own creative process that I've never shared," Jennifer writes. "While writing and recording are certainly a major part of my work, it is the performance element with which most folks are familiar. How I approach performing, how I rehearse, as well as my ethos on my relationship with the stage and the audience are all elements that I imagine will be displayed in this show. That is a peek behind the curtain and consequently, makes me a little nervous."

She gives a few tips to potential contestants. "I'm looking for big voices, males and females, who can sing diverse, dynamic music," she writes, making a strong bid for male singers. "Guys, I need you too!!! I have to find the yin to my yang. The ebony to my ivory. The Captain to my Tennille."

Jennifer is no stranger to powerful duets, having shared the stage with Bon Jovi ("Who Says You Can't Go Home"), Lady Gaga "(You and I") and Matt Nathanson ("Run").
