Destinee & Paris Belt Out Adele and Gnarls Barkley (VIDEO)

What do you get when you combine two smash-hit songs with two up-and-coming ladies with some serious pipes? You get one fabulous mash-up video, and Celebuzz has the clip of artists Destinee & Paris going all-out on Gnarls Barkley’s “Crazy” and Adele’s “Rolling in the Deep.”

The blonde beauty sister duo (17 and 15 years old, respectively), who have opened up for pop megastars like Lady Gaga and Mariah Carey as they continue their ascent to similar success, tell Celebuzz that they decided to mash up the two songs both live and in the video above because they wanted to create an interactive atmosphere with their fans in the crowd.

“It was really important to us to have that moment where we can connect with the audience, so we chose to cover two of our favorite songs and create a medley of ‘Crazy’ by Gnarls Barkley and ‘Rolling in The Deep’ by Adele, which is great because everyone in the audience is really familiar with the songs,” Paris told Celebuzz.

Her parter-in-pop sister Destinee, who plays the piano throughout the medley, said that she and Paris “always thought that the two songs sounded similar,” so one thing led to another, and voila: A musical pop mash-up emerged.

“The audience loves it and we have a blast performing it! It’s amazing having thousands of people sing along with you!” Destinee tells Celebuzz about the reaction when they perform the medley live.

This isn’t the first time that Destinee & Paris have hit a homerun with a smartly-adapted cover. Their rendition of Lady Gaga’s “Born This Way” has racked up more than 650,000 views on YouTube, and they’ve also done takes on Jessie J and others. Watch “Born” below!
