Heidi Klum's Cheeky Instagram Dance Video Goes Viral.

Supermodel Heidi Klum, 49, shared a cheeky video on Instagram, showing off her dance moves and shaking her bottom in a figure-hugging gold dress. She playfully stuck her tongue out and flicked her blonde locks while the Kim Petras track Alone played in the background. The video ended with her strutting away as though on a personal catwalk. Klum recently posed in a bright yellow bikini and matching bucket hat during a sun-soaked getaway with her husband, Tom Kaulitz.
