Take current teen fave Justin Bieber and the cast of "Glee." Add Reese Witherspoon and J.K. Rowling. Mix in some Easter eggs and, oh yes, the First Family and a bunch of children and what do you get.

It’s the 2010 version of the Annual White House Easter Egg Hunt.

President and Michelle Obama Monday are welcomed a star-studded cast to the annual festivities, along with 30,000 parents and children from all 50 states. But this year there wasn’t just the usual Easter Egg roll, but performances, story readings and music from a cast that also included Sara Bareilles, Apolo Ohno, Mariska Hargitay, Dylan and Cole Sprouse, family-oriented singer Billy Jonas and "Yo Gabba Gabba" and "Sesame Street" characters.

Here’s a look at some of the big performances that took place on the White House’s South Lawn.
