In the final and perhaps the most intriguing battle on 'The Voice' before the live competition, country crooner Curtis Grimes took on punk rocker Emily Valentine in a rendition of Lady Antebellum's 'Need You Now.' But it would soon appear as if the two Cee Lo Green team members were sharing more than just a song.

"Singing with Curtis is bittersweet," said Valentine when she heard she would be battling against the country singer. "We've been really close so far in the friend side of the competition."

"It's a very unique pairing," said Cee Lo. "They come from opposite ends of the spectrum."

Apparently, opposites attract, as Valentine admitted she had a "little crush" on Grimes. In fact, Valentine told PopCrush in a recent interview that she was a sucker for his "old southern charm." Grimes, meanwhile, also admitted that he and Valentine "had gotten pretty close."

When they entered the ring, the wholesome looking Grimes and the tattooed Valentine seemed like they had no business being onstage together. But toward the end of the Lady Antebellum ballad, the two started to peer into each other's eyes. But they saved the best part for last. When the song was over, Grimes took off his cowboy hat and planted a long kiss right on Valentine's lips!

Blake Shelton had the best line of the night when he said, "Cee Lo probably told y'all to duet, not do it!" However, it was Cee Lo's decision that mattered, and he ended up choosing Grimes. For now, the apparent lovebirds will have to part ways, with Grimes heading to the next round and Valentine going home.
