By
Former Bachelor star Sean Lowe and his wife Catherine are parents!
The couple welcomed their first child, a son named Samuel Thomas, they announced on Saturday. 
"God is good! We had a healthy baby boy named Samuel Thomas. Thank you everyone for your prayers and support!" Sean tweeted on Saturday. 
Catherine quickly followed up with an announcement of her own: "I'm in love with another boy, my son Samuel Thomas Lowe."
Just before the birth, Sean tweeted that the baby was coming. "He's coming. Or maybe she. But someone is coming. And mama has never looked more beautiful."
On Thursday, Catherine posted side-by-side images of her growing baby bump as she chronicled her pregnancy journey on Instagram. "BREAKING NEWS: I'm still pregnant," she adorably captioned the pic.

The couple's pregnancy news was first announced in December.

"It's happening!" Sean wrote on Instagram along with a photo of him massaging Catherine's belly. "I'm going to be a dad!"
"Sean and Catherine are very excited," a source close to the couple told ET at the time. "She's about three months along - due early summer."
Sean and Catherine got engaged during the 17th season of The Bachelor and tied the knot on Sunday, Jan. 26, 2014, during a ceremony officiated by Sean's dad, Jay.

The couple made more room for their plus one two weeks ago when they got a new house.

"Just about settled into our new home," Catherine tagged an Instagram photo of herself at her new doorstep.
