Hamlin did not acknowledge the viral tweets or the status of his relationship with Fish, who is often mistaken as his wife.
While his social media features countless photos of the couple’s two daughters, the NASCAR racer rarely shares photos with his partner.
Hamlin and Fish share daughters Taylor James Hamlin, 8, and Molly Hamlin, 4.
The duo first met in January 2007 at a Charlotte Bobcats game where Fish was performing as a member of the Lady Cats, the Bobcats dance team.
At the time, Hamlin was sitting court-side when they locked eyes.
They went their separate ways after the game, but many months later, Fish approached Hamlin and asked him to sponsor her for the Miss South Carolina USA pageant.
He agreed and as a thank you gesture, Fish took Hamlin out to dinner, and the pair have been dating ever since.
