Chrissy Teigen is looking beautiful and "fitter than ever."
In the first photo, Teigen looked over her shoulder as Legend helped her get the perfect shot by fixing her hair. The model and bestselling author looked chic in a form-fitting black dress with dramatic thigh-high slits on both sides, which she paired with strappy stiletto heels and silver hoop earrings.
In the second snap, Teigen posed solo, showing off her toned legs and supermodel pout.
Fans applauded the leggy London look and begged the star to share her workout routine.
"Oh wow, this is a stunning look!" commented a fan on Instagram. "Your legs are out of this world!"
"Can you please let me know what your workout routine is? I want to know how I can get your legs and booty!" wrote another before adding a fire emoji. "Looking fitter than ever."
"Holy smokes, those are some legs for days! Love that your husband John helped you get this shot — husband duties done right," said another.
"You guys are constantly the best dressed couple on the planet. I'm in love," gushed another fan.
Later that evening, Teigen changed into a little black dress with a floor-length sheer blazer and knee-high boots for dinner at The Ivy in London.
"Good mushy peas and bathroom light at the ivy," she captioned a bathroom selfie, which was met with an influx of comments that dubbed the model "stunning and sexy."
"Not fair! Tell us your secrets!" pleaded a fan on Instagram. "You look fire."
"Stunning and sexy girl! A gorgeous model inside and out," wrote another.
"You're out of this world. Looking stunning, fit and amazing as ever. I'm gonna go hit the gym now!" added another.
