Former 'Bachelor' Stars Sean Lowe and Catherine Giudici Are Expecting a Baby

— -- The "Bachelor" family is expanding.

Former "Bachelor" stars Sean Lowe and Catherine Giudici are expecting a baby.

"It's happening! I'm going to be a dad!" Lowe wrote next to a photo of himself touching Giudici's stomach in their Instagram announcement today.

"Hey baby," wrote Giudici next to a similar snap.

Lowe, 32, and Giudici, 29, met and got engaged on "The Bachelor" in 2013. In January, 2014, they were married in a televised ceremony, and a few months later, Giudici told ABC News that they weren't antsy about having children just yet.

"We admire babies and children. We look at them and say, 'I like you,' but it's not in our hearts yet," she said. "We talk about it constantly though. I'm really curious to see what they look like!"
