"I've grown a thick skin that it does not bother me so much anymore, but when someone constantly does it, you can't help but notice these horrible messages."
Lexi said she was incredibly blessed to have had an easy pregnancy, but every woman's journey is different and it is unfair for bullies to try and break someone else down.
"Each and every woman experiences pregnancy differently. Weight gain, break-outs and all the symptoms of pregnancy are perfectly normal. Don't allow some random comments to get to you. Embrace your flaws and protect your space," said Lexi.
Despite being faced with such negativity, nothing can take away the joy Lexi is feeling while waiting for the arrival of the couple's bundle of joy.
She revealed that they've decided not to find out their baby's gender.
Even though Lexi would not be drawn into revealing when their bundle of joy was set to arrive, she said her hospital bags were packed already, "so it could be any day now".
Lexi said she was looking forward to every aspect of motherhood.
"God has chosen me to take care of a human being, I'm such a perfectionist but I am looking forward to the little chats we'll have, the fun times - it's just so weird because we (Mandla and I) are going to have a little human running around the house demanding whatever he or she wants.
"But we're ready," she said.
