The 32-year-old mother of three took to her Instagram Stories on Sunday to share a behind-the-scenes look from a Christmas shoot.
“This is pure moisture,” Teigen says in the video, showing off a large wet stain on her girdle as she poses in a matching bra. “We’re pretending it’s Christmas, and it’s so hot out. This is sweat. Look at my bra!”
Teigen then lifted up her bra a tiny bit to show off even more of the sweat. She later dried off a bit and posted a video of herself getting dolled up in the hair and makeup chair, flashing some cleavage and sporting a bold red lip.
The final look featured Teigen in a festive hot pink strapless gown with a large bow that looked like something Marilyn Monroe would have worn.
