Viral Sensation Sophia Grace Is Now A Teen Making Music With Silento

But what about Rosie?

One-half of the adorable British girl duo who went viral in 2011 after covering Nicki Minaj's "Super Bass" (then got a boost from multiple appearances on Ellen DeGeneres's show) is now out with her new single.

Sophia Grace Brownlee, now 13 years old, released "Girl in the Mirror" on Friday (June 10), which features Silento of the "Watch Me Whip/Nae Nae" fame.

The song, available now on iTunes, shares an empowering message for girls to accept who they are and actually like the person in the mirror: "'Cause every setback's just a setup / For something just a little bit better," Brownlee sings.

"Girl in the Mirror" marks Brownlee's third single after "Girls Just Gotta Have Fun" in 2013 and "Best Friends" in 2014. She also performed music for her and her cousin Rosie McClelland's movie, Sophia Grace & Rosie's Royal Adventure.

And while her hype girl Rosie isn't in the new music video, the 9-year-old is taking singing classes, meeting Spice Girls, and is still BFFs with her cousin.
