still isn't over for Fergie
and new husband Josh Duhamel
Asked to name her favorite part of her Jan. 10 wedding
in Malibu, Fergie – who was performing at Thursday night's 5th Annual Black Eyed Peas Peapod Foundation Benefit Concert Presented by Adobe Youth Voices at L.A.'s Conga Room – enthusiastically replied: "Saying I do!"
Hitting the stage with the Black Eyed Peas, Fergie (real name: Stacy Ferguson), 33, rocked the 1,000-strong crowd with some of the band's biggest hits, including "Pump It" and "Shut Up" – as her new groom watched from the wings by the bar, sipping a Heineken, chatting with friends and pumping his fists in the air as he admired his wife's performance. Rihanna
made a quick visit too, watching from the audience toward the end of the night.
