Bachelor Nation has another citizen! Season 17 Bachelor Sean Lowe and his wife, Catherine Giudici, have welcomed their first child.

The LoweCo. stationery designer, 30, gave birth to a son, Lowe announced via Twitter on Saturday, July 2. "God is good! We had a healthy baby boy named Samuel Thomas," the proud new dad wrote. "Thank you everyone for your prayers and support."

Giudici added in a subsequent tweet: "I'm in love with another boy, my son Samuel Thomas Lowe."

On Friday, Giudici teased the imminent arrival of their little one on Twitter. “It is time,” she wrote, crediting Rafiki from The Lion King for the quote.

The new parents — who met on The Bachelor in 2012 and married in a televised wedding in January 2014 — announced on December 8, 2015, that they were expecting. “It’s happening!” Lowe, 32, captioned an Instagram shot of the couple. “I’m going to be dad!”

In the months after, the couple faithfully documented Giudici’s pregnancy on social media. In February, both reality stars shared pictures of a sonogram. “The good news: baby is perfectly healthy - praise God!” Lowe wrote. “The bad news for both baby and mom: baby apparently has a big head like daddy. But how freakin’ cute is my wife?”

The lovebirds, who live in Dallas, later enjoyed a babymoon in Palm Springs, California, where they’d spent a memorable weekend together after The Bachelor finished filming but before the finale aired.

“To this day, we still talk about how much fun we had just hanging out at that house, swimming, grilling and watching movies,” Lowe wrote on his blog prior to the babymoon in mid-April. “So next week, we’re going to try and recapture those memories and make some new ones too.”

That same month, the couple talked with Us Weekly about preparing for baby. “He is the most loving and wonderful daddy to our doggies, and I know it will be exponentially better when it’s our own child,” Giudici said at the time.

Added Lowe: “I’m most looking forward to the challenge of being as good of a father as my dad was, and still is, to me,” Lowe said at the time. “Over the years, my dad has proven time and time again that he will support me and be there for me no matter what … That’s what I want to give my child as well. I want them to know that their dad will always be their biggest supporter.”
