We love January Jones and her spunky sense of humor. Following the icy blonde on Instagram is a total delight with her sexy pictures and cheeky captions. She recently got extra cheeky with a picture of her, well, cheeks. That's right - we're talkin' about her ass.

Jan proudly showed off her booty-hugging shorts that show us a little bit of underbun as she manned the grill. We definitely want to touch the chef's buns! Shame on her sister for wanting her to change clothes, but Jan looks good no matter what she's wearing. Thereare plenty of skintillating pics on Mr. Skin that prove that.

Follow January Jones on Instagram for more sexy pics. Sometimes she gets playful and shows us some cleavage like in this "dressed-down" picture. If this is her dressed-down look, then January is the hottest woman in the world.
