Sophia Grace meets Magic -- in a tutu, of course ...

Nine years old and already a British singing phenom, Sophia Grace Brownlee and her six-year-old cousin Rosie McClelland have gone from YouTube sensations to the Grammys to The Ellen DeGeneres Show -- where they rapped with Nicki Minaj.

The next stop on their tour de force was Dodger Stadium -- in tutus, of course -- to visit Magic Johnson and throw out the first pitch before Monday's game against the D-backs.

As Ellen herself so neatly put it, "1, tutu, 3 strikes you're out at the ol' ballgame."
