The superstar songstress used her skills in front of the camera (and her drop dead gorgeous looks!) to advertise her hubby's luxury range, which includes a number of expensive wardrobe items, jewellery and ski masks.
In one snap, Beyoncé can be seen wearing an oversized, black and white Moncler varsity jacket, which she has teamed with one of the all black snapback caps from the collection and a pair of sunglasses.
Her blonde locks are tied up and she is also sporting some gold jewellery.
Beyoncé simply captioned the photo: "Jay Z collection at Barneys", letting her millions of fans know that the high-end items are now on sale.
Another Instagram picture shows Queen B wearing a two-finger gold 'New York City' ring designed by her rap star husband, while placing her hand over a Barney's holiday catalogue.
But you might want to rethink before you start saving up your Christmas money to purchase some bling like Bey, as this ring alone comes with a hefty price tag of over £7700!
A final Instagram image sees Beyoncé modelling one of the Shawn Carter collection luxury ski masks in a slightly eery black and white shot.
Although Jay Z's collaboration with Barneys might be pretty pricey, 100% of the money made from sales will go towards providing scholarships for underprivileged youth through the rapper's Shawn Carter Foundation.
Meanwhile, Beyoncé was also spotted having some down time with her busy husband at a basketball game this week.
Yesterday (21 November), the parents of Blue Ivy were pictured sitting court side at a game in Oklahoma City and they couldn't stop smiling all evening.
