The video has been viewed more than a million times since being uploaded to YouTube on June 4, with the caption:
"'You can't do much in the ninth month of pregnancy... but you CAN spoof Iggy Azalea's 'Fancy' ;)"
The video was made by the ladies behind popular American YouTube channel WhatsUpMoms. They reworked Iggy's lyrics, so her original chorus of:
"I'm so fancy. You already know. I'm in the fast lane from La to Tokyo."
"I'm so pregnant, you already know. I'm in the last month. I can't even see my toes! I'm so pregnant. Can't fit in any clothes. Don't ask me the name. I don't know."
Meg Resnikoff, the Los Angeles-based co-founder of What's Up Moms, has two children under five and was nine months pregnant when she starred in the video, so she's speaking from experience.
She told TODAY.com that her least favorite thing about pregnancy is "all those strangers caressing my belly." While her favourite thing is: "Those trips to the doughnut shop after each doctor's appointment!"
Come on now sing along...
"First thing first I'm the roundest. They don't ask but the whole world feel it. Please don't feel it And I pee every 10 seconds. I cannot bend down - that would defy the laws of physics."
