While the reality duo has yet to publicly comment on the speculation, during a recent double date with sister Khloé Kardashian and French Montana in New York City, the 35-year-old beauty was seen sipping ginger ale, instead of wine.

In the past, Kourtney has candidly expressed her love of motherhood and desire to have more children. “Nothing comes before my children,” she told Mini magazine. "Having an amazing partner, Daddy, doesn't hurt either.”

E! News reports that Kourtney is likely to address the pregnancy rumors during the premiere of “Keeping Up With the Kardashians” on Sunday, June 8.
