AceShowbiz - Is Keke Palmer having a bun in the oven? Fans of the actress portraying Emerald Haywood in "Nope" are convinced that she's pregnant after they noticed a visible belly button and her cryptic Instagram post.

Internet sleuths spotted that Keke's belly button is sticking out after the 29-year-old actress posted a Halloween-themed TikTok video on Thursday, October 27. In the footage, she dons a striped red, white and black sweater that looks pretty baggy on the stomach area.

When making some moves to avoid Ghostface, Keke's belly button appears to stick out. Generally, most pregnant women's belly buttons pop out because their uterus has significantly grown to make room for the baby.

In the comment section of Keke's TikTok post, many noticed Keke's appearance changes. "Just announce this pregnancy," one person wrote. Another quipped, "Save you and the baby Ke runnnnnnnnnn."

"Keke let these ppl know you will announce your pregnancy when you are ready," someone else commented. A separate person said, "Yeah the pregnancy is too obvious at this point lol."

Another TikTok user added, "I'm gonna say I think she is. I live in over sized sweaters, they give a chic cool girl look, but this sweater is for hiding a belly…" In the meantime, another suggested that Keke may be pregnant with "a boy baby," pointing out at Keke's so-called pregnancy glow.

A few hours after posting the TikTok video, Keke turned to her Instagram page to share a series of her new selfies and a throwback photo of her when she's baby, prompting many to think that she's subtly announcing the alleged pregnancy. "Last one my faaaaave," so she captioned the post.

"are you giving a hint?? u pregnant?!!" one person reacted. Another chimed in, "Face is getting chubby too. The announcement is coming!" Someone posted, "And the full face pregnancy glow??? I'm watching too."
