Fergie to Rock the Easter Egg Roll

Fergie singing at white house easter egg roll

Move over First puppy Bo -- some headline competition will arrive to the White House today.

Superstar Fergie is teaming up with reggae master Ziggy Marley and children's favorites SteveSongs and Imagination Movers to perform for 30,000 people at the annual White House Easter Egg Roll. Chefs Art Smith, Spike Mendelsohn and Jose Andres will also teach guests how to cook healthful foods, as actors James Cromwell and Josh Duhamel put their public speaking skills to the test by reading to tots in attendance.

Several celebrity athletes -- including basketball, football and soccer stars -- have also agreed to lead games and interact with guests at the event, a White House tradition since 1878.
