Joe Guidice shaded his ex-wife Teresa Guidice after she posted a picture of herself posing with the sister of her now-husband, Luis Ruelas.
He penned in the post's comment section, "I thought you loved Melissa," highlighting Teresa's ongoing feud with the Gorgas.
Shortly after, he deleted the statement and wrote, "Beautiful."
In the post, Teresa celebrated her sister-in-law Veronica Ruelas, who was turning a new age.
Joe previously called out Luis last year after he posted a yoga picture of himself on Instagram.
Teresa recently shared in a post that it was "just too hard" to continue watching the "RHONJ."
She blamed her decision on her brother and his wife's continuous negative comments about her.
In an Instagram post weeks later, Teresa bragged about her relationship with Luis' sisters.
At the time, fans criticized her for not forging a strong bond with her brother's wife, Melissa.
