"It's a gooey, silly love kinda day," the Big Bang Theory starlet captioned one photograph, along with plenty of heart emoji icons.
The 28-year-old, casual in a T-shirt and her hair in a bun, smiles as she gives her hubby a kiss on the cheek. The 26-year-old is grinning widely as he gets some love from his ladylove. The duo is at home, as evidenced by their beloved dogs resting comfortably in the background.
And speaking of the couple's precious canines, the blond beauty posted another snapshot hugging her beloved pet.
"Happy Valentines Day to the other man in my life! #norman," Cuoco-Sweeting wrote along with the loving photo.
In addition to the photos snapped on the holiday, the actress shared a throwback with her "partner in crime."
The tennis pro and his wife enjoyed a romantic meal, and Sweeting wished the "love of his life" a Happy Valentine's Day.
Wishing the newlyweds a wonderful celebration!
