Blake Shelton took the stage again, this time pumping things up a bit, when he was joined with fellow 'The Voice' judge Shakira for their duet of 'Medicine.'

Shelton's co-host Luke Bryan introduced the two with a joke about the fact that he was surprised they teamed up together for a song on her album. "I was amazed because of the language barrier," Bryan says as he brags about Shakira's ability to speak four languages. He joked that after just two beers "Blake just has trouble with one."

This was Shelton's second time performing and he definitely picked things up! Shelton wore a vest with jeans and his left arm tattoo exposed, while Shakira made her 2014 ACM Award debut looking feminine in a red dress and knee high boots. She brought out her Colombian beauty with red lipstick -- she even went a little country with big hair.

Their stage chemistry is undeniable; the two look born to sing together. The crowd seemed to enjoy the performance as they danced and sang the words to 'Medicine.' Shelton and Shakira faced each other as they sang the song, before taking the edge of the stage by storm. Shakira made sure to end the performance with a bang -- she flipped her hair (a la Taylor Swift) before they embraced for an end of song hug.
