Following in the footsteps of Justin Bieber and Chrissy Teigen, who both bared their derrieres for the Gram, Kate Upton flashed her bare bum too just for the heck of it.
"Happy Sunday! #buttday #bruceweber #sundayfunday," she captioned the shot Sunday, which showed her walking in a field in a sheer black dress with her bum completely visible through it (how did we miss the memo about butt day?!).
Of course, Kate's Sunday Funday wasn't all about flaunting her booty. The supermodel also took time out to hang with a French Bulldog named Soy – he has his own Instagram, which says he's the assistant to celebrity photographer Yu Tsai. And no, Kate didn't give him any tips on how to pose for this shot. He's clearly a pro, as evident from his leisurely pose with his paw perfectly placed for the snap.
Kate went more casual for this shot, ditching the butt-baring dress for a gray t-shirt (and hopefully bottoms). Talk about getting cheeky.
