Wearing a skin-tight white dress and Santa hat, the brunette beauty showed off her impressive post-baby body in a matching waist trainer in the mirror selfie.

"Just when I thought my waist couldn't get any smaller IT DOES!!! Breast feeding + @Instacurve_ Waist Trimmer work wonders," she wrote.

This photo comes just days after Chyna's private messages were leaked on her social media account, prompting Rob to share the heartbreaking news of their split.

"I can't believe she did this to me. And this isn't for some ratings this is my real life so please understand I'm just being open right now. Cuz if it was for ratings I wouldn't explain all this here. And with Chyna's messages and her leaving with everything and the baby I am broken. I go 1000 percent for my girl. I am so confused how a man who gives and loves everything about a woman is the one left alone."

He continued, "I am so broken. This is a woman I fought my entire family for. I was in love with this woman to the fullest and I was none of that to her."

Along with calling Rob "lazy, fat and insecure," Chyna also revealed her plans to trademark the name Angela Renee Kardashian behind Kris Jenner's back.

However, Chyna spoke out against the hack, and accused Rob of abuse.

"Rob begged me to have Dream," she wrote. "He stressed me out my ENTIRE PREGNANCY!! Accusing me of cheating, going crazy on me with massive text blast daily… I was verbally abused every other day. I was still there with nothing but high hopes for us."

"I'm done with the situation until he gets help," she added. "I have 2 children and myself to fend for. What hurts the most is watching him do this to me knowing my last situation and promising me never to put me through it."
