Is she nuts?!

Kourtney Kardashian took son Mason and daughter Penelope to Toys R Us yesterday to pick up some water guns, and we can't believe she was wearing a sweatsuit. California is in the middle of a heat wave! We guess this is what you call privilege, because she probably goes from one air conditioned space to another all day long, so she doesn't need to plan her outfits accordingly.

We've gotta hand it to Kourt and her sisters for donating $500K to the Hurricane Harvey relief efforts. Her charitable contribution makes us feel inclined to put up with more of her bikini selfies. The reality star works out daily with sister Khloe, and can't stop showing off the results of her slim down on Instagram.

The mother-of-three has a pretty tight tushy these days! Boyfriend Younes Bendjima is a lucky man!

tip of the day: don't forget to stretch 😝
