Sophia Grace And Rosie Rap On 'Ellen' Show: Girls Sing, Freestyle To Keri Hilson's 'Turn My Swag On' (VIDEO)

British starlets Sophia Grace and Rosie have made yet another triumphant return to "The Ellen DeGeneres Show," this time rapping to Keri Hilson and doing some freestyling of their own.

In the video above, the girls sing to Hilson's "Turn My Swag On" right before Sophia Grace erupts into a clever freestyle describing the duo's recent rise to fame.

"We're going to the top of Hollywood, and it's official, but dad's in the crowd crying, here's a tissue," the British starlet belts out. "And it don't stop, we're flying to the U.S. from the U.K. non-stop."

It didn't take long for the audience to fall in love with them all over again.

Sophia Grace and Rosie received a standing ovation, and Ellen surprised the girls with news that they will be interviewing celebrities on the red carpet at the Grammy's -- with new puffy, pink dresses nonetheless.

Sophia Grace Brownlee, 8, and cousin Rosie, 5, became Internet sensations after a video of the pair singing Nicki Minaj's "Super Bass" went viral on YouTube in September.

Today, the clip has been viewed more than 30 million times.

Since then, the girls have regularly appeared on "Ellen" and even interviewed stars at the American Music Awards as correspondents for the show.
