Bachelor Nation's Sean and Catherine Lowe Are Expecting Baby Number 3 . . . but When?!

The Bachelor's Sean Lowe and his wife, Catherine, are expecting a third baby! The Bachelor Nation fan-favorite couple got married in 2014 after Sean's season of the show, and have since welcomed Samuel Thomas, nearly 3, and Isaiah Hendrix, 1. Now, the Lowes are going to be a "#PartyofFive," and we're so excited for the adorable family.

Based on the timing of the announcement — and the fact that most expectant moms typically tend to wait until they're out of their first trimester to share pregnancy news — we'd guess that baby number three could arrive any time between November and January.

Congratulations, Lowe family!
