Don’t call her Stacy anymore…

Fergie has legally changed her name to Fergie Duhamel, according to People magazine.

The 38-year-old part-Mexican American Black Eyed Peas singer, who was born Stacy Ann Ferguson, married her husband, actor Josh Duhamel, in 2009 but just recently petitioned for the name change.

Fergie, who performed a song for The Great Gatsby soundtrack, and Duhamel are expecting their first child, who is due in the fall.
