We may still be waiting for Khloé Kardashian to publicly confirm her pregnancy, but that didn't stop her from dropping some subtle hints on last night's Keeping Up With the Kardashians. The episode, which was filmed four months ago, shows the reality star going on a wine tour with her sisters Kourtney Kardashian and Kendall Jenner.

While Kourtney and Kendall were clearly enjoying their time in the vineyard, Khloé is noticeably refraining from drinking her wine. "You both are wasted and I'm not," she said on the show. "I'm so not on your level, but I'm willing to take one for the team. You guys are having the best time and I love watching you guys having so much fun." Interesting…

If you need even more proof Khloé may have known at the time she was expecting her first child with Tristan Thompson, viewers only needed to look at her full wine glass, which Kendall happily finished for her. "Oh, Khloé's is left," Kendall giggles before drinking it up. The timing of the episode also coincided with a Snapchat story that the 34-year-old posted, which referred to her NBA boyfriend as "dad."

Khloé is said to be five months pregnant, and already dealing with food cravings. She is reportedly determined to avoid overeating as to not completely ruin her revenge body. "She is being extra healthy right now," a source told E! News. "So far her pregnancy cravings have been sugary foods. She loves Oreo cookies."

Earlier this season, Kim Kardashian confirmed her pregnancy via surrogate on the reality show. Kim, 37, told Khloé the exciting news over FaceTime while cameras rolled. "We're having a baby," Kim said. So fans can expect a Kardashian baby boom in 2018, as Kim, Khloé, and Kylie Jenner are all due within weeks of one another!
