Fergie, a member of the Black Eyed Peas, sang “Clumsy” at the 2009 White House Easter Egg Roll. She performed at the event on April 13, 2009, during Barack Obama’s first year as president.
The White House appearance included more than one musical moment. Fergie also sang the national anthem, which President Obama praised in his remarks, and performed songs from her solo career. “Clumsy” was one of those songs, making the performance notable because it brought a contemporary pop hit to a family-oriented presidential event.
“Clumsy” was released as a single from Fergie’s 2006 debut solo album, The Dutchess. The song uses a playful theme of awkwardness in romance and became one of the album’s major hits. Although Fergie is best known in group trivia as a Black Eyed Peas vocalist, this particular performance came from her solo catalog. That distinction is why the answer is Fergie rather than the group’s name.
