Something's definitely different!

Khloe Kardashian posted this photo to Instagram yesterday, and almost immediately, her fans began speculating that she'd secretly gotten a nose job. While we admit her shnoz looks way thinner, we think it might just be good contouring. We doubt she'd go under the knife with a bun in the oven!

Speaking of which, the reality star is reportedly feeling hotter than ever during her pregnancy, and it's really making things fun in the bedroom with boyfriend Tristan Thompson.

"Khloe’s feeling very sexy right now, she’s never had boobs this big in her life and she’s having a lot of fun with it. Her sex life with Tristan hasn’t slowed down at all and she’s planning to keep it that way. She just went on a crazy lingerie spree and dropped over ten thousand dollars on new stuff to wear in the bedroom and around the house while she’s pregnant," a source dished to Hollywood Life.

"Most of what she got isn’t even maternity wear, she got a lot of see through robes and even some corsets that can expand right along with her bump. She’s keeping things very hot in the bedroom, they’re having fun,”the source added.

We're still wondering why she and sister Kylie haven't announced their baby news though?
