The cutest little British rappers you will ever see are back ... and this time they hit the Grammy red carpet to interview music's biggest stars!

Sophia Grace Brownlee, 8 and her cousin Rosie McClelland, 5 have gone from internet sensations to bona fide TV stars thanks to Ellen DeGeneres' fondness for the tykes. First seen belting out Nicki Minaj's "Super Bass" on YouTube, Ellen has since brought the girls on her talk show where they've performed several times, met Nicki and even covered the American Music Awards for "Ellen." Now they've just completed their biggest task yet -- the Grammy red carpet!

The adorable girls donned gold and pink tutus and had a "bubble party" with Lady Antebellum, belted out "Moves Like Jagger" for Maroon 5, and got hugs from Rihanna, Katy Perry, Taylor Swift and more. Covering a huge awards show can be exhausting, so they even paused for a sandwich and juice box break on the red carpet. Too cute!
