People who've seen the viral video version of her belting Adele's "Rolling in the Deep" knew Air Force Staff Sgt. Angie Johnson could sing. They might not have known, until Tuesday night, that she's drop-dead gorgeous.

When Johnson blew the roof off her blind audition for NBC's "The Voice," singing Pat Benatar's "Heartbreaker," only judge-mentor Cee Lo Green turned his chair around to recruit her for his team. But that was enough, assuring that Johnson continues in the competition.

"Are you as beautiful as I think you are?" Green said after seeing Johnson. "Let me put on my reading glasses." He then pulled out a huge pair of sunglasses and put them on. "I love a woman with guts, with power, with confidence," Green said later.

"I let Cee Lo get away with something," judge Blake Shelton said, telling Johnson he almost hit his own button to turn his chair around, the signal on "The Voice" that a judge wants to recruit a singer for his or her team.

"You were, the whole time, on pitch. Like you were really, really good," judge Christina Aguilera said, applauding. "And that's a tough song."

Johnson, 31, from St. Louis (she grew up in St. Ann), now lives in Nashville. Host Carson Daly personally recruited her for "The Voice" after seeing her Air Force band, Sidewinder, in the video that racked up more than 1 million hits on You Tube in just over a week.
