Bikini Body by Baby.

Baby bumpin’! Catherine Giudici is basking in her babymoon. The first-time mom-to-be shared an Instagram photo of her growing belly in a bikini on Wednesday, April 20.

“Bikini Body by Baby,” the former Bachelor contestant, 29, captioned the poolside snap.

Giudici’s husband, Sean Lowe, whisked her away on the pre-baby trip to Palm Springs on Monday, April 18. “Babymooning with my sweetheart this week,” he captioned a snuggly looking Instagram photo. 

"It will give me a good excuse to get away for a few days," the season 17 Bachelor, 32, blogged about their trip. "So this Monday, Catherine and I are heading to Palm Springs, California. We picked Palm Springs for a couple of reasons — it’s warm and sunny, and it also holds some sentimental value with us."

Lowe explained that following their time on The Bachelor, they secretly visited with each other in Palm Springs. "To this day, we still talk about how much fun we had just hanging out at that house, swimming, grilling and watching movies,” Lowe recalled. “So next week, we’re going to try and recapture those memories and make some new ones too."

Lowe and Giudici tied the knot in a televised ABC wedding in January 2014. The couple announced to Us Weekly last December that they are expecting their first child.
