Heidi Klum was the pioneer of the 'bodysufring' selfie craze last year, but she's taken it to a whole new (totes inappropes) level with her latest snap.
The model and 'America's Got Talent' judge posted a pic of her actual bum crease on Twitter. Yes, you heard.
She was sunning herself on a beach in the Bahamas when she pulled down her bikini bottoms to reveal her errrm, bottom as she showed fans her burn tan lines.
"Ouch!" she simply posted alongside the photo.
But for fans of the more conventional Twitter bikini snap, Heidi also posted a picture of herself frolicing in the waves, showing off her new dreadlocks.
"Thank you for another beautiful day in paradise," she wrote as she posed in the monochrome two-piece.
Looking cracking, Heidi.
