Nicki Minaj's unique personality has led some to describe her as "inimitable," but as it turns out, that's not quite right.

Last week, 8-year-old Sophia Grace Brownlee scored a viral hit with her YouTube cover of Nicki's 'Super Bass,' nailing both the nimble rap verses and big pop chorus. The performance landed the tiny singing sensation on today's (Oct. 12) episode of 'Ellen,' and as if a national TV appearance wasn't exciting enough, Sophia got the surprise of her young life when the wig-wearing MC herself emerged from backstage.

"Within five seconds of seeing this video I was calling everyone," the 'Pink Friday' creator told host Ellen Degeneres, describing Brownlee's YouTube clip, which has been viewed more than 7 million times. "I was also receiving a billion emails. Everyone was like, 'You have to see this little girl.'"

After Nicki big-ups Sophia's silent 5-year-old cousin Rosie Grace, calling the younger of the tutu-clad tykes a "hype girl," the hip-pop superstar offers the girls some valuable career advice.

"I just want you to stay in school," she says. "Music is beautiful, but stay in school, OK? Put your books first and singing second."

Nicki then joins Sophie for a 'Super Bass' duet, letting the young Barb bogart the spotlight. Princesses have got to stick together.
