Blac Chyna’s name has been mentioned dozens of times on “Keeping Up With the Kardashians,” but the model has yet to make an appearance on the E! reality show. Well, according to a new report that’s about to change. Chyna is said to be filming scenes for an upcoming Season 12 episode.

Sources told Us Weekly that Chyna, 28, is not only currently filming for the show, but will also appear in scenes from Khloé Kardashian’s 32nd birthday party, which was held Monday at Dave and Busters in Los Angeles. This week it was reported that the pregnant model, who’s engaged to Rob Kardashian, was seen at the bash with her beau and his family as they celebrated Khloé’s big day. Kylie Jenner, who’s once again dating Chyna’s ex Tyga, was also at the party and even posed for photos with her.

On Sunday’s episode of the reality show, Rob sits down with his sisters Khloé, Kourtney and Kim Kardashian to talk about his surprise engagement to Chyna. The 28-year-old sock designer and Chyna announced they were engaged in April, but kept he Kardashian family in the dark about it. In last week’s episode, Rob keeping the engagement a secret from his family caused some drama among them. “It happened like spontaneously so that’s why you guys weren’t in the loop,” Rob explains in a sneak peek of the upcoming episode 9. “Because I was gonna do this regardless, I just didn’t know when and it just ended up happening.”

Rob and his siblings were able to patch things up, but the clip ends with him dropping another bombshell about his and Chyna’s relationship. “There’s one more thing I have to talk to you guys about,” he says. “I don’t want you guys to get mad.” Even though the clip ends before Rob could reveal his news, it’s obvious that he’s going to tell them about Chyna’s pregnancy. The model, who hasn’t revealed the sex of her baby, is said to be due in October.

In addition to Chyna reportedly making her “Keeping Up With the Kardashians” debut, she and Rob are also documenting her pregnancy for an E! show tentatively titled “Rob & Chyna.” The couple’s docuseries is set to premiere later this year.
