The two models dressed up as Mrs Santa and then tweeted the pictures.
Heidi Klum, 38, posted a picture of herself on Twitter in a Santa costume, writing “Mrs. Claus going to work.”
The Project Runway host was clad in a leg-baring sexy red and white costume, while standing in an elevator.
Back in October, she chose a unique costume for Halloween: a skintight “Visible Woman” costume.
“It’s kind of like a dead body with the first layer of skin ripped off,” she explained at the time. “It’s basically like me naked.”
For her part, Imogen, 29, dressing up in the mood of the season while cooking a Christmas dinner in her kitchen.
The model posed in a red and white fur-trimmed strapless dress and thigh-high stockings.
She posted the picture on Twitter under the caption Xmas time. “Lush day.”
