"Two years ago today I said 'I do' to the man of my dreams," the 26-year-old captioned the shot. "This last year has been amazing and heart breaking all at the same time and I am so thankful for the man who stood by my side. I am so lucky that my kids get to call you dad and even more blessed that I get to call you mine."

Fans flooded Zach and Tori's comments section, gushing over how cute they are together. Many of them wished the couple a happy anniversary, and many others speculated that Tori is pregnant again because she wrote "kids" instead of "kids" in the caption. "Happy anniversary Zach [and] Tori, but wait did you say 'kids' meaning you're pregnant?" one fan wrote.
