"Yesterday, my sweet wife posted what we both thought would be a funny April Fools prank on Instagram…Most people knew immediately that it was a joke of course and that she wasn't really pregnant," he said on his blog earlier today.
"On nearly every picture Catherine posts on Instagram, she gets flooded with comments from people who tell her she looks pregnant. We understand that many of these people have no ill intent and are genuinely just hoping that we're pregnant because they want to see us start our family, and we totally get that.
"But at the same time, it would be really tough for any woman to hear that 'she looks pregnant' on a daily basis when she's not…So that was the genesis of yesterday's post, it was playing off of the bombardment of pregnancy comments she reads every day and messing with those who post them."
Lowe continued, "I understand there are a lot of people hurting out there who are struggling with fertility and they are left with feelings of worry, frustration, and anger. I get that. But my wife's Instagram is not the place to voice those feelings.
"If you know anything about Catherine or have followed her for any length of time, then you know that she is one of the most caring, compassionate people you will ever meet. If you are one of those who are struggling with fertility, I promise Catherine's heart breaks for you."
