"She is the happiest girl on earth," a source tells PEOPLE
“Fergie called a lot of her girlfriends today to tell them the news,” a source close to the singer told PEOPLE. “She said they don’t know what kind of wedding they want yet, but that she is the happiest girl on earth.”
The Las Vegas star’s rep would say only that they got engaged “recently,” but not on Christmas. TMZ.com first reported the engagement news Wednesday.
Fergie was seen sporting a diamond ring on her all-important digit back in November, during the American Music Awards, but her rep denied the engagement rumors then. The couple celebrated Duhamel’s 35th birthday last month with lots of love and little fanfare.
