As if we weren’t already head over heels in love with YouTube sensations Sophia Grace Brownlee and Rosie Grace McClelland, this video has certainly pushed us over the edge. Ellen enlisted the girls to work the red carpet during Sunday’s Grammy awards (clad, of course, in their famous pink tutus) and Sophia and Rosie managed to interview a slew of stars, from Rihanna to Fergie to Flo Rida. Our favorite part is when Sophia Grace exclaims to the camera, “I bet you any money that Taylor Swift, when she comes up, she’ll be wearing gold, because gold really suits her!” And of course, Sophia was right.

In short: This is a must-see. Watch the full video after the jump.
