She's ignoring the haters.

Kourtney Kardashian took son Mason to grab frozen yogurt yesterday, and at first we thought the reality star forgot her pants, but then we realized she was just following that hideous biker shorts trend. Is athleisure over with yet? We're sick of it!

Speaking of being partially clothed, the reality star was recently mom shamed over a nude pic she posted in honor of fitness week on her app. Although all you see is part of her bare bottom, commenters went nuts slamming her for daring to bare all when she has kids.

"Real classy, Mother of 3, 4, 5, 6,? I wonder what would you children say when they see this," one person wrote.

If she needs some comforting, sister Kim knows all about this subject!
