Fergie isn't just a stage persona anymore -- she's officially changed her name from Stacy Ann Ferguson to Fergie Duhamel after a judge gave the sign off on Friday.
Fergie -- who's been married to actor Josh Duhamel for nearly 5 years -- requested the name change last month, claiming she wanted it for a bunch of reasons ... not the least of which is that no one ever calls her Stacy.
Fergie had to publish a notice in a local newspaper for four weeks (just like Ron Artest before he became Metta World Peace), which she dutifully did.
And just like that, she's a new person -- at least legally.
