Some of Khloe Kardashian's fans are not convinced that she is expecting after seeing her in her Halloween costume.

Kardashian dressed up as Daenerys Targaryen for Halloween this year, while her boyfriend, Tristan Thompson, went as the husband of the mother of dragons, Khal Drogo. The "Keeping Up with the Kardashian" star's "Game of Thrones"-themed attire exposed her midsection, so her fans immediately looked for her baby bump. However, some were disappointed when they did not see it, sparking speculation that Kardashian may not actually be pregnant.

"I don't see no baby bump," Instagram user Chasidyari commented on the photo of Kardashian in costume.

"I don't think she's pregnant," another user wrote.

"She doesn't look prego to me," Pepricka commented in the photo (via Daily Mail).

Another user said that the pregnancy reports were perhaps just rumors. "Maybe.. JUST MAYBE... she's not actually pregnant and it's all just made up rumors," littlehufflepunk wrote.

Meanwhile, another follower suggested that Kardashian is not that far along in her pregnancy so she is not yet showing. "I don't really know. She could only be a few months which would explain why she is so small still," the user wrote.

In September, it was reported that Kardashian and Thompson are expecting their first child together. The couple has not yet addressed the pregnancy rumors, but they had been hinting about their desire to start their own family for months. The "Kocktails with Khloe" star admitted that they want to have a big family and that the NBA star is already excited to be a dad.

"He wants to have kids now," Kardashian said of Thompson. "He said, 'I want to have kids with you, [and] if you get pregnant, you could make maternity jeans for [your clothing line] Good American."

Kardashian also confessed that she is no longer taking birth control pills. She is scared but excited about her future with Thompson. "He wants to have like, five or six kids with me, and that's lovely. We could start at one and then grow from there. But now, knowing I'm not on birth control, it's really scary. It's like a really big step," Kardashian added. "I am really, really excited about my future with me and Tristan. We're doing so well, and I'm looking forward to see where all that goes."
