Alison, 36, took a moment to show her love for Dave on his 34th birthday.
"Happy Birthday to my whole heart ❤️," she wrote under a selfie with her man on Instagram.
The pair met in 2011 while attending Mardi Gras in New Orleans.
They dated for three years before they engaged in August 2015.
Though the two are happily in love now, the How To Be Single actress admitted she didn't initially say yes when Dave popped the question! She told People in 2017, “I was so shocked that I actually burst out laughing, and I asked him a number of times if he was being serious before saying yes."
In March 2017, the couple made things official during a small, intimate ceremony.
