While many women might run from the idea of sporting a pair of flares, 33-year-old Jessica proved that the risky wardrobe item can look smart and fashionable when worn right.
She was pictured leaving her hotel in Manhattan on Wednesday (29 January) and gave a sweet smile for the cameras, before heading out in her all-black get up.
The songstress teamed her tailored flares with a cropped leather jacket that featured a warm, shaggy collar and donned a pair of black high heels - although they were barely seen under her trousers!
She accessorised with a gorgeous black studded handbag and a pair of round sunglasses, while keeping her blonde hair poker straight.
Jessica also added a blinging set of diamond earrings by Lanvin to her look for an extra glam factor. We can see them sparkling from a mile off!
Following the birth of her second child, Ace Knute, in July last year, the yummy mummy has been working hard to achieve her ideal post-pregnancy figure.
And her recent stylish ensembles are proof that those rigorous gym sessions and her new Weight Watchers diet were all worth it.
Jessica has been spotted out in leather trousers, a sizzling red floral dress and various other items that flatter her post-baby body over the last few months and is now on the hunt for the perfect wedding gown to flaunt her figure in.
Speaking about her upcoming nuptials to fiancé Eric Johnson on USA Today last month, she said: "I've been pulling all kinds of sketches for dresses and colours. It's a good goal for me. It's good for me to feel the best I've ever felt when I walk down the aisle."
