That hoodie may be huge, but it's still not enough to cover up Khloe Kardashian's supersize lips!

On Monday the reality starlet hit the gym in Los Angeles, and while sister Kim was getting all dolled up for the Met Gala, Khloe was busy busting her booty at Gunnar Peterson's workout center. And maybe after that she went home to hang with brother Rob Kardashian? We have to wonder what's going on with those two...

Even though Rob is reportedly closest to Khloe, it seems like he may be wearing out his welcome at her mansion. Kim and Khloe had a chat on the latest episode of Keeping Up With The Kardashians, and not only did Rob throw a party with "major whores" in attendance, but a disgusted Khloe told Kim, "Someone threw up in my house." Ew!

Kim's response? "He won't leave the house or see us, hardly, but he'll have parties and see other people?" Khloe nodded and added that she finds Rob's life "so bizarre." But will she kick him out? Or will they save that for next season? After all, it's all about Bruce this year!
