"Oh my goodness it seems the stork is visiting us again!!!!" she captioned the adorable black-and-white photo, which shows her beaming and holding her belly. "I am growing another little Tyler Gardner in my belly. Our family is growing!!! So grateful. @davidgardner i love you."
Gardner also took to social media, sharing a pic of Tyler showing off her baby bump on the beach. "My beautiful baby is pregnant !!!!," he wrote. "Sooooooo excited and so blessed, I love you @misslivalittle."
Tyler and Gardner welcomed their first baby together, Sailor, less than a year ago in February 2015. Tyler is also mom to 11-year-old Milo, who she had with ex-husband Royston Langdon. Gardner also has an 8-year-old son, Grey, from a previous relationship.
