The 36-year-old supermodel was spotted with dark rings under the armpits of her grey T-shirt, proving she had really put some effort into her workout.

The Brazilian beauty teamed her tee with black leggings and black Under Armour sneakers and she tied a grey sweatshirt around her waist.

The statuesque stunner, who stands just an inch under 6ft, tied her dark blonde tresses back into a ponytail.

She didn't have a scrap of make-up on, allowing her beautiful complexion to shine.

Gisele's pal was similarly dressed in a grey T-shirt, black dropped leggings, and bright blue sneakers with her light blonde hair also styled in a ponytail.

On Sunday he made his much anticipated return to the NFL team after his four-game suspension following the Deflategate scandal.

Gisele is usually in the crowd watching, but on this occasion she stayed home with the children and watched it on TV, sharing the moment that Vivian cheered when she saw her dad on the screen on Instagram.
