Last September, Petty announced that she and her husband had welcomed their first baby together, son Beau, sharing the news on her Instagram. The Survivor star posted an Instagram video of herself, Jackson and their newborn son on their couch, cuddling together.

“Out of everything I’ve ever done, this is by far the best. I don’t have the words to fully encompass everything, but it was perfect,” Petty wrote in her caption.

“Our birth was beautiful, we are doing great in postpartum. Everyone’s healthy and happy and he’s the most perfect thing I have ever seen. I’ll be soaking these snuggles in for the foreseeable future.”

“This is everything I’ve ever dreamed of and so so so much more. Thank you @jacksonraypetty for the baby and this life; I love you so much. Oh, and his name is Beau and he’s a libra,” she said.

That May, Petty shared that she was expecting her first baby as her season of Survivor was airing. Posting a carousel of pregnancy photos, Petty stripped down to bare her belly, leaning against a tree in one photo. She also posed with her husband, standing together alongside a pond.

“I’ve gotten really good at keeping secrets and going on adventures this year, but it’s finally the perfect day to tell y’all WE’RE HAVING A BABY!!” Petty wrote in her caption. “Sweet lil Petty popping up in September.”
