Heidi Klum showed support -- or a lack thereof -- for Germany ahead of their UEFA Euro 2020 opener on Tuesday .... by showing off some serious underboob as she wished the squad good luck!!
The 48-year-old supermodel gave an incredibly sexy shoutout to her home country's football club ahead of their match against France ... saying quite simply, "Good luck today Germany."
Klum threw on a pair of black bikini bottoms, a gold waist chain and a cropped Germany jersey for the special message ... and giving a big smile and two thumbs up to the camera.
