For a couple of months now, Khloe Kardashian has been silent about her rumored pregnancy, leaving fans in the dark as to whether or not she is expecting a child. However, the socialite herself may have confirmed the rumors through a social media post of a pic of her boyfriend with a very telling caption.

On Monday, the television personality went on Snapchat and posted a photo of her NBA player boyfriend Tristan Thompson at Lebron James' Halloween party. She captioned the photo "That's daddy," which fans are taking as a confirmation of her pregnancy.

The costumes that the couple donned at the party also seem to thread a very telling line of comparison. Thompson came as Khal Drogo from the HBO show "Game of Thrones," while Kardashian came as his wife Daenerys Targaryen, who is also known by her alias as the Mother of Dragons.

Kardashian posted multiple photos of themselves, showing the amount of detail that went into their costumes. The couple wore plenty of fur and leather to match their counterparts from the fantasy television show.

She also posted a photo of themselves sharing a passionate kiss while sporting their medieval attire and long wigs. The other party-goers also showed their appreciation for the couple's intricately made costumes. They took home the Best Couples Costume award of the party.

Sources have confirmed to UsWeekly that the starlet is indeed expecting a baby boy with the NBA forward. "She's hungrier than ever," said one source, who also added that Khloe "opts for smaller meals throughout the day."

The source also revealed that the relationship between the couple is going very well, with marriage a big possibility. "Marriage is definitely in the cards," the source said. "They are just waiting for the right time to move forward. Khloe doesn't want to rush into anything."
