The mum-of-one was spotted walking the pink carpet in Sin City for the Magic Market Week Convention yesterday (19 February) and dressed up in a cool, smart-casual outfit - complete with eye-catching accessories.
She layered a long grey cardigan over a zebra print T-shirt and donned a pair of her trusty leather trousers.
Is it just us or does Fergie love her leather bottoms just as much as Kanye West?!
The Black Eyed Peas songstress finished off her Vegas look with a pair of gladiator-esque heels and tousled hair.
And of course, she added an edgy twist by stacking her fingers with plenty of silver rings.
As well as an ornate skull, Fergie sported a couple of long silver finger accessories that made it seem like she had swapped her hand for a metallic claw.
And to top it off, she painted her pointy nails in a striking silver colour too.
After attending the Magic Market Week Convention, 38-year-old Fergie let her hair down at a Britney Spears show.
Britney is currently performing in Sin City as part of a residency at the Planet Hollywood Resort and Casino, which will run until 2015.
Unsurprisingly, fellow pop star Fergie - who gave birth to her first son Axl last year - had a great time at the gig and tweeted afterwards: "Ms Brit #youdrivemecrazy."
But unfortunately, the feisty songstress didn't get on stage and join in the fun like Nicole Richie had done the previous night.
On Tuesday (18 February), Nicole performed on stage with Britney during her track 'Freakshow' and was even pictured crawling on all fours, surrounded by dancers.
Well, not everyone would have the guts to do that!
