The 29-year-old 'Call My Name' hitmaker took to Twitter to reach out to the 32-year-old to make sure she is holding up during her pregnancy, reported Daily Mirror.
"Dear Kim. Hi gorgeous lady. Just wanted to send you a tweet to say 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! I admire your tenacity and send you my best wishes with the rest of your pregnancy," Cole posted.
