The Duck Dynasty flock is growing.

Sadie Robertson, the third-eldest of Korie and Willie Robertson‘s six children and the granddaughter of Duck Commander founder Phil Robertson, and her husband Christian Huff announced on Feb. 14—Valentine’s Day—that she is pregnant with their third baby.

“Our hearts are so full,” Sadie wrote on a joint Instagram post shared on the couple’s pages, alongside a photo of the couple sitting together with their daughters, Honey, 3, and Haven, 20 months, and holding a sonogram. “Another little love joining the Huff family.”

The 27-year-old’s mother, Korie Robertson, commented, “Soooooo excited!!! Very best blessing.”

Sadie’s sister-in-law Mary Kate Roberston, wife of the Dancing With the Stars alum’s brother John Luke Robertson, also expressed her well wishes. “THE BEST!!!!” she wrote in the comments section, adding a red heart emoji.

Sadie and Luke’s sister Bella Robertson Mayo, 22, added, “BEST NEWS!!!!!! cant wait!!!”

One day later, Sadie shared a photo of herself showcasing her baby bump in another post.
