The Keeping Up With The Kardashians star shared a series of polaroids from her 33rd birthday in June, where she could be seen feeding her NBA player boyfriend cake in an image she labelled "Dad + Mom."
Another potential clue came as recently as last week, when the star shared a gif from the reunion special that was filmed in April. After taking a sip of champagne, she could be seen cursing "oh f**k!"
Multiple sources have confirmed the news that the couple, who have been dating since September 2016, are expecting their first child to People, TMZ and more.
"Yes, Khloé and Tristan are expecting and they are absolutely thrilled," a source tells People. "This isn’t something they were in a rush to announce to the whole world, and it’s only been in just the past week or so that they’ve felt comfortable telling most of their inner circle."
The baby will be a first for Khloé, who spoke openly about her desire to have children and her fertility struggles on KUWTK. Meanwhile, Tristan welcomed a son named Prince Oliver with an ex-girlfriend in December 2016.
Khloé's baby news came just days after her younger sister, Kylie Jenner, was reported pregnant. Older sister Kim Kardashian West has also been reported to be expecting, as she and Kanye West are apparently pregnant via surrogate.
Despite all the reports from these typically reliable publications the Kar-Jenner family are yet to confirm or deny the news, with the exception of Caitlyn Jenner who spoke out via her rep. We'll be waiting to hear from the women of the family before we go throwing any baby showers, though we're so excited for Khloé and Tristan should this turn out to be true.
