Everyone's favorite guest star from The Ellen Degeneres Show is all grown up—and she wants people to know it.

In 2011, Sophia Grace rose to viral stardom when she appeared on television in an adorable pink outfit and rapped along to Nikki Minaj's hit song, "Super Bass." The British singer's debut performance racked up more than 34 million views on YouTube and kickstarted her childhood fame. But now, nearly a decade later, the 15-year-old is ready to put her tutu and tiara days behind her.

Sophia Grace recently released a new song titled "Can't Sleep," and the teen is practically unrecognizable in the sassy music video.

"People were saying they want me to be the same as I was before," she says at the beginning of the track. "It annoys me because I'm not that person anymore and they always ask me to go back to how I was, but I'm different and that's not who I am, so I want to show people that I'm a different person now and I've changed, but that's okay because everyone changes."

In the video, Sophia Grace traded her "fluffy dress" of years past for a sportier look accompanied by large hoop earrings. The only noticeable nod to her 8-year-old self was the color of her long nails: hot pink.

The viral performer's transformation got us wondering about the other half of the pint-sized duo that we fell in love with. Sophia Grace's cousin, Rosie McClelland, was only five years old at the time they appeared on Ellen and barely spoke as her senior sidekick stole the show. Years later, she has finally found her voice. Rosie is now an actress, singer, dancer, and model, and recently released a song of her own. The single, titled "Handstand," has more than 5 million views on YouTube.

Even the woman who made these two into pop culture stars can't believe how much they've grown. On Ellen's 60th birthday show, she shared a sweet video message she received from Sophia Grace and Rosie. The talk show host seemed just as shocked as we are that the once-miniature singers are all grown up.

"That's when you feel the aging, because you see them age and then you compare it. So now, I feel old," she joked.

You're not the only one, Ellen!
