The couple, who have been dating since September, exited the restaurant walking hand-in-hand with Brinkley showing off her beaming smile.
Brinkley looked stunning in a long floral wrap dress and accentuated her long legs in a pair of suede knee-high boots.
~The purest and most hopeful heart that I have ever known / She thrives upon wonder, optimism, goodness / She calls nature and family her home / She spots the masterpiece in everything / She makes paintings in her coffee-cup / She sees pictures in the sky / Her faith in human kindness is what wields her golden shine / She's the most tireless mother, model, entrepreneur, philanthropist, and artist that one could be / So thank you, precious Mom / For devoting your life to cultivating love / And for granting so much of it to me.~ ❤️❤️❤️ -Your Eldest, Musette #HappyBirthdayMamacita #ATopTen #InBodyHeartAndSoul
The mother of three received many well wishes from fans on social media and a few shout-outs from her daughters as well.
The 30-year-old singer helped kick off the birthday celebrations on Sunday along with family and friends, even gifting Brinkley with a birthday cake that had a picture of her wearing a Mellencamp concert tee.
