Heidi Klum flashes underboob while supporting Germany in the Euros

To mark her home country playing in a huge sporting event, supermodel Heidi Klum treated fans to an eye-popping photo.

Heidi Klum has proved that age is definitely just a number after the supermodel flashed her cheeky side in a recent Instagram post.

In celebration of her home country, Germany, playing against France in the UEFA European Football Championship (also known as the Euros) on Wednesday, the 48-year-old treated fans to quite the display.

The mother-of-four sported a cropped team jersey that appeared to be strategically ripped across her chest, leaving for an ample amount of underboob to show.

“Good luck today Germany,” Heidi captioned the image.

She posed outside for the photo, going make-up free, with her thumbs up and hair tossed to the side.

The America’s Got Talent judge completed the look with black string bikini bottoms and a gold chain worn around her waist.

She also took to her Instagram Stories sharing various photos and videos while watching Germany compete, including one with her rear to the camera, wearing very – very – short, shorts.

She appeared to be enjoying her time, indulging in pizza and beers with her husband Tom Kaulitz, 31.

The underboob and racy shorts, however, didn’t help as Germany lost 0-1, with Heidi ending her entertaining stories with a congratulations post to France.

During a photo shoot for Vogue earlier this year, the model took a quick break to give her 8.1 million Instagram fans a quick glimpse of her booty.

The funny clip shows the former Project Runway host wearing a very tiny pink G-string and quirky toilet paper dress as she glances over her shoulder.

At the time, Heidi revealed she was taking part in a new challenge set by Vogue as she added #VogueCouchCouture to her post.

She also shared a snap of her outfit next to Valentino’s actual creation and a short clip flaunting her at-home look.
