The Bachelor's Sean Lowe and his wife, Catherine Giudici—whom he met and proposed to during Season 17 of the reality show—will now officially join Jason and Molly Mesnick and Trista and Ryan Sutter in the infamous dating show parenting club.

They are expecting a baby!

The couple—who have pretty much lived out their entire relationship in the public eye—announced Giudici's pregnancy on their Instagram accounts, natch. "It's happening! I'm going to be a dad!" Lowe, 32, captioned a photo of himself lovingly touching his wife's belly.

Giudici, 29, shared a similar shot, punctuated with the succinct but perfect caption "Hey baby :)."

The couple joins Bachelor/Bachelorette-alums-turned-parents Jason and Molly Mesnick, who are parents to 2-year-old daughter Riley, and Trista and Ryan Sutter, who have 8-year-old Maxwell and 6-year-old Blakesley.

"We are so thrilled to announce that we're expecting!" Lowe and Giuduci told Life & Style. "Thank you all for the love and support you've given us over the years. We can only hope to be half as good of parents as are our parents were to us."

After meeting on The Bachelor in 2013, Lowe and Giudici tied the knot in a live, two-hour made-for-TV wedding last January. The reality stars have also appeared on Celebrity Wife Swap, and they are currently participating in Marriage Boot Camp: Reality Stars.

Congratulations, you guys!

This will be the first child for the happy couple, who has not yet released any information regarding the baby's due date or gender.

If it's a girl, may we suggest the name...Rose?
