KoKo’s lips are zipped…for now, at least. Even though Khloé Kardashian has yet to confirm her pregnancy, the reality star — who is expecting her first child with boyfriend Tristan Thompson — has no problem calling the hunky NBA player “daddy.”

The expectant Keeping Up With the Kardashians star, 33, took to Instagram on Thursday, Dec. 7, to share a photo of herself rocking a fishnet sweatsuit from her Good American clothing line. In the comments section, Khloé tagged Tristan, 26, and wrote, “hey daddy,” accompanied by four red heart emojis.

This isn’t the first time the Strong Looks Better Naked author has called Tristan “daddy” on social media. Back in October, when the parents-to-be dressed up as Game of Thrones characters for Halloween, Khloé posted a Snapchat video of Tristan, with “that’s daddy” written across the screen.

Khloé’s sweet nickname for Tristan seems to prove just how excited she is to start a family with the Canadian-born athlete. On last season of KUWTK, the blonde beauty said that she is looking forward to first-time parenthood — despite the fact that she’s a little nervous.

"Tristan and I definitely talk about starting a family,” the former Kocktails With Khloé host said. "[Tristan] wants to have five or six kids with me and that's lovely. We could start at one and we could grow from there. But now knowing I'm not on birth control is just like — it's scary. It's like a really big step.”

News of Khloé’s pregnancy broke in September. Since then, the E! personality has flaunted her tiny baby bump on several occasions. Most recently, she showed off her growing belly in a clip posted on sister Kourtney Kardashian’s snapchat. In the video, Khloé put her bare tummy on display in a black crop top.

Keeping Up With the Kardashians airs on E! Sundays at 9 p.m. EST.
