The mother of two liked a post from her manager Sharon Finnigan which read:
'It's funny how you're nice to my face. It's hilarious how you talk s**t behind my back. And it's downright comical that you think I'm unaware.'
The liking of the post comes after Joanna—who is the wife of Sam's brother, George— claimed Phoebe has "never joined the Burgess side of the family" for Christmas.
The post drew criticism from her followers, suggesting she did not care for her sister-in-law.
"You made a comment as though you had no care in the world for your sister-in-law," one angry Instagram follower commented on the post.
It was the inability to show compassion and humility that caught the attention of your followers because however close you might be now with your husband and his family, another in very similar circumstances was suffering," they continued.
Joanna's most recent admission comes after she shared a photo of the annual Burgess family Christmas lunch, captioning the picture "was the best one yet."
Fans were quick to point out that Phoebe was absent from the picture, prompting many to write that she was taking an obvious swipe at the WAG. Joanna later clarified that it "is not in my nature to take a dig at someone."
"Phoebe has never joined the Burgess side for previous Christmas festivities. Therefore it couldn't possibly be aimed at her," she said.
"My last year's Christmas upload I used a similar caption as it was our son's first Christmas. This year we had our daughter join the three of us, hence it being the "best one yet'," Joanna signed off.
Things between the Phoebe and Joanna seem to have been hostile for some time now. Phoebe recently unfollowed both she and her husband on Instagram. Shortly after, Joanna did the same to Phoebe.
In recent weeks, reports have surfaced that Sam and Phoebe split during the holidays, three years after tying the knot in a beautiful Southern Highlands wedding.
