The 32-year-old posted a selfie with the caption, "sleepy" on her Instagram late in the evening.
But while Kardashian was catching some much-needed Z's, another famous brunette was speaking out in her defense from across the pond.
Cheryl Cole took to her WhoSay account to send the pregnant star a message, saying, "Hi gorgeous lady! Just wanted to send you a tweet to say I think you are an incredibly beautiful woman inside and out.."
"I can only imagine how tough it is to be heavily pregnant and feeling extremely vulnerable on top of some of the daily criticism you take!" she added. "I admire your tenacity and send you my best wishes with the rest of your pregnancy #enjoyyourblessing x"
Well, it sounds like Kardashian's got a fan in Cole for life!
