In what could be a publicity stunt, reality-TV star Rob Kardashian says in a series of Instagram posts that fiancee Blac Chyna not only broke up with him, “but she took the baby also and she took my eggos and my chips and my sweet baby rays BBQ sauce” with her.

The lengthy messages were posted Saturday, with the “Baby Special” episode of the couple’s show “Rob & Chyna” set to air the next day. Blac Chyna, using a new, second Instagram account on Sunday, posted a promotional clip, captioned, “Everything would be explained after the show tonight,” followed by a heart emoji.

The episode featured the Nov. 10 birth of their daughter, Dream Renee Kardashian.

“This wasn’t fake or some publicity stunt,” Kardashian, 29, insisted in one Instagram post. “Trust me.”

Kardashian began posting after Blac Chyna, 28, wrote Saturday on Snapchat that her new Instagram account had been hacked. According to People magazine, the alleged hacker’s messages spoke of Blac Chyna’s discomfort with Kardashian and plans to leave him and take their daughter.

“Chyna took her and left this beautiful home that I just bought for us. Right before Christmas,” Kardashian wrote. “Someone I have given my all too. I Loved every inch of that woman and loved everything that came with her. I truly loved Angela,” he said, alluding to her birth name, Angela Renee White. “I gave everything I owned for her. Didn’t know I was just part of her plan. I really believed she was in love with me the way that I was with her and I am so hurt and never felt this before.”

In her own lengthy posts, since removed but transcribed by People, Blac Chyna wrote, “I’M DONE. This entire year I have done nothing but help Rob! . . . Rob begged me to have Dream! He stressed me out my ENTIRE PREGNANCY!!! Accusing me of cheating, going crazy on me with massive text blast daily! being an absolute lunatic & then cover it up with gifts! I was verbally abused every other day.”

She added, “I PUT MY PRIDE ASIDE & I GAVE UP MY HOUSE TO MOVE INTO KYLIE’S HOUSE WITH HIM TO BE WITH A MAN!! . . . AND I NEVER NOT ONCE CHEATED ON ROB! EVER! I gave him the passcode to my phone I have nothing to hide. He refuses to do anything! Eat healthy, work out, work, anything positive, he does nothing!”

Blac Chyna’s mother, known as Tokyo Toni, wrote in a series of her own Instagram posts, “#RobKardashian on his situation with #Chyna. #Publicity stunt or #Real life?” And a since-deleted message, transcribed by Us Weekly, hyped the TV episode: “Things about to get really, really heated up on this show. This is one of the best shows ever on TV. It’s not going anywhere.”
