Katrina Parker wasn't one of Adam Levine's favorite contestants when she joined his team at the beginning of 'The Voice' Season 2 -- and he made that clear in his assessment following her Monday night performance. Tonight, he said she was "flawless."

The 34-year-old Parker, who was previously saved from the bottom three, dazzled with a powerful performance of Christina Perri's 'Jar of Hearts,' and none of the judges had too much to argue about, as they all agreed: she was great.

She definitely did what she came to do and "sang the crap out of her song." Standing in the center of the stage, in a giant pink heart with her blonde hair flowing and a purple dress just touching the floor, Parker kicked things off for Team Adam like the American version of Adele. Needless to say, she was flawless.

From the first notes, her coach had his eyes closed in his red chair, but he wasn't sleeping -- he was moved. Following the number, Blake Shelton, who spoke first, was speechless. "That was awesome," he said, adding that she was sweet, powerful and "totally different from anybody else."

Christina Aguilera, who made it clear that she's against the comparisons to Adele, told her, "You're Katrina Parker -- and own that." Cee Lo agreed with Shelton, admitting, "it's like seeing and hearing you for the first time."

As for Adam, he didn't sugarcoat his critique. She may not have been one of his favorite team members when they started, but she is now. "I'm so proud," he said. "You've evolved so much. That was incredible. Flawless."
