"Three months ?? ? and a #mcm all rolled into one .. here’s to you my darling," Cuoco captioned the pic of her in a white dress grinning at Cook, who opted for a pink collared shirt, jeans, and silver bracelets.
Cook, 27, also celebrated the milestone. In a hilarious video posted to his Instagram, Cuoco lovingly grooms Cook's face as he jokingly laments, "Why am I not good enough for you?"
"Your brows aren't, you are," Cuoco quips back.
"This video is just pure marriage, plain and simple," Cook captioned the clip. "I believe there will be a time when @normancook looks at me with love. For the foreseeable future she only sees problems with my face?"
