Jessie J

In 2011, Erato, a female vocal trio comprised of Ebba Lovisa Andersson, Amanda Wikstr m and Petra Broh ll, covered Robyn's 'Call Your Girlfriend' using just their voices and a few plastic cups.Now, two young sisters are doing their own version of Erato's cover of Robyn's song, armed with just two empty plastic containers and a couple of microphones. The result is simply amazing. As you'll see from their names floating above their heads, the girls are called Lennon and Maisy. They are only 12 and 8 years old, respectively. (Paging Ellen DeGeneres!)Big sister Lennon is the main vocalist, while little sister Maisy provides the harmonies. To put that into perspective: even adult singers struggle with harmonies, so the fact that an 8-year-old has mastered them is pretty impressive. To watch more of Lennon and Maisy's covers, click through the gallery below. Lennon 12 and Maisy 8 sing their version of Jason Mraz's I Won't Give Up. These girls are truly amazing.

Tyra Banks goes way overboard with her makeup, Rumer Willis attempts "homeless chic" and Jessie J in all white!

Jessie J and Team Xtina start the festivities off right with their take on "Domino."
