Yet, Upton rarely posts photos of this nature on Instagram. Instead, she often gives fans a behind-the-scenes look at her professional life. On Sunday, she uploaded a photo to promote her role as the new celebrity spokesperson for Bobbi Brown Cosmetics. 

The photo shows Upton smiling while wearing one of the brand's red lipsticks. "Happy #WorldKissDay! I'll be celebrating w/ my favorite new @BobbiBrown color, Vintage Red," Upton wrote as the caption.

Bobbi Brown explained the reason for choosing Upton to replace former spokesperson Katie Holmes.

"I admire women who create their own rules, so I was naturally drawn to Kate because she's a maverick who has carved her own path to success," Brown said in a statement.

"Kate is proud of her healthy body and has a beautiful face for makeup," she added. "She is a real woman, a natural beauty, athletic, and radiates confidence, but doesn't take herself so seriously. She's having fun and enjoying life, and that is pretty powerful."
