Underwood's "Before He Cheats" won Best Female Country Vocal Performance and Best Country Song (awarded to songwriters Josh Kear & Chris Tompkins) honors.
Last year, the American Idol fourth-season champ took home two Grammy awards for Best New Artist and Best Female Country Vocal Performance for "Jesus Take the Wheel."
While "Before He Cheats" lost Song of the Year honors to Amy Winehouse's "Rehab," the song continues to receive recognition from both the music industry and fans.
Although it was awarded in the pre-telecast ceremony (less than a dozen of the 110 awards were presented during the CBS broadcast), Underwood still personally accepted her Best Female Country Vocal Performance honor.
"You couldn't keep me from actually getting this myself, it's not the same when someone else gets this on your behalf," said Underwood.
Daughtry's band was hoping to capture its first Grammy award after receiving four nominations, however it apparently wasn't meant to be for the former Idol 5 finalist.
The group's self-titled debut lost Best Rock Album to "Echoes, Silence, Patience & Grace" by the Foo Fighters, while the single "It's Over You" lost Best Rock Song to Bruce Springsteen's "Radio Nowhere." "Home" -- a ballad that served as background music for Idol sixth-season eliminations -- lost to The White Stripes "Icky Thump" in the Best Pop Performance By A Duo Or Group With Vocals category.
In addition, the album's producer Howard Benson lost Producer of the Year honors to Winehouse's producer Mark Ronson.
Fantasia Barrino also missed her chance to claim her first Grammy, as her second album "Fantasia" lost in the Best Contemporary R&B Album category to "No One" by Alicia Keys. The Idol third-season champ's debut album "Free Yourself" received two 2006 Grammy nods in the Best Female R&B Vocal Performance and Best R&B Album categories, however she failed to receive either award.
However another former Idol 3 finalist -- Jennifer Hudson -- continued her hot streak. The Dreamgirls' song "Love You I Do," which was written by Siedah Garrett and Henry Krieger and performed by the Oscar winner in the film, received Best Song Written For Motion Picture, Television or Other Visual Media honors.
Underwood's "Oh Love" duet with fellow country crooner Brad Paisley and original Idol winner Kelly Clarkson's "Because of You" duet with best bud Reba McEntire was defeated in the Best Country Collaboration with Vocals category by Willie Nelson and Ray Price's "Lost Highway."
Idol 5's ninth-place finisher Mandisa Hundley also saw her debut album "True Beauty" loose in the Best Pop/Contemporary Gospel Album category to "A Deeper Level" by Israel And New Breed.
