“The amount of bullying and hatred I've had to put up with for three years ... I'm tired of looking at it. Be kind. Be gracious.
“We are grown-ups ... stop acting like teenagers. Real women don't put down other women,” she added.
Jess, whose twin boys served as page boys at Meghan’s royal wedding, initially shared the snap with the caption: “When I feel dark and grey, I see this and it all goes away.”
The 40-year-old later replaced the caption with “I see this and pure joy.”
It’s thought Jess may have posted the snap of her son to profess her friendship with Meghan, but the photo's mysterious disappearance has only added fuel to fire that there is a rift between the pair.
Jess’ comments come after it was reported the former BFF is allegedly fearful the royal will throw her “under the bus”.
“Jess is worried Meghan needs a scapegoat to blame for all the stories that get leaked to the press about her,” a source recently claimed.
“Meghan can’t really argue to a right to privacy if her friends are speaking out about her. But Jess is worried she’ll make it seem like it was Jess who was acting on her own accord.”
Jessica and Meghan reportedly fell out recently after the Canadian fashion stylist was called out for racism toward Toronto-based blogger Sasha Essex.
