She's not letting her bun in the oven slow her down!

Khloe Kardashian has taken a lot of criticism for working out while pregnant, but the reality star could care less what her haters think, because she continues to post videos of herself exercising with sister Kourtney on Snapchat. We're not sure why her fans are so concerned that her fitness routine is going to harm the baby, because most people know it's totally safe, but we're proud of her for sticking to her guns.

One user wrote that heavy exertion could cause "trauma" to her unborn child, and she was quick to clap back.

"No it cannot! My doctor has instructed me to do so. Why does everyone on social media think they are a physician?? Why would I do anything to do that? If you don’t know mind your own business," she wrote on Twitter.

The Revenge Body star followed her response up with a link to a Fit Pregnancy article about the benefits of working out while expecting. "For the ones who think they are physicians all of a sudden but MY doctor and I communicate and my workouts are cleared and highly recommended," she added.

Go Koko!
