However, a source tells ET that Kardashian is not married.
"The rumors spread are made up and false," the source tells ET. "Khloe is in a committed relationship and very much in love, but they are not married."
The source adds that the couple is focused on a healthy pregnancy and did not secretly wed.
The speculation started nearly immediately after Kardashian's announcements, with fans quick to point out the bling and ask about her relationship status.
"Also two rings on her finger, is she married? #KhloeKardashian," on Twitter user wrote, with another tweeting, " Wait?!! What!! So is @khloekardashian engaged/ married too ? I see the ring 😱👌🏽👌🏽💗💗 💍💍."
While Kardashian did not say if she was indeed a married lady in that follow-up tweet, she has been spotted with diamond bands on her commitment finger before. In fact, she rocked them in May while attending the NBCUniversal Upfront event in New York City.
She was also spotted wearing a similar ring in October when she celebrated the launch of Good American at Bloomingdale's in NYC.
"Khloe and Tristan are doing so great and have an incredible relationship," the source revealed to ET at the time.
"Khloe doesn't need a title to make their relationship real, and she doesn't want to mess up how perfect it is now," the source added. "She's already done the marriage thing [with now ex-husband Lamar Odom]. Getting engaged is not something she's sitting around stressing about. If it happens, it happens..."
