Dennis, 58, shared a painting of himself wearing his Chicago Bulls jersey as he rode a majestic-looking horse.
The retired NBA player captioned it, "Lets. Ride. ? @lilnasx." He tagged the rapper and added an eggplant emoji.
Lil Nas, 20, replied to the post, "lmfaoooo."
The flirty caption had fans wondering if the basketball player was coming out of the closet. One user took to the comments and asked, "Is Dennis coming out of the closet? ?"
Another wrote, "Oh n***a u gay." One fan commented, "ARE. YOU. GAY. ?. JUST. A. QUESTION."
Lil Nas opened up about his sexuality on June 30, the last day of Pride Month.
He tweeted, “Some of y’all already know, some of y’all don’t care, some of y’all not gone fwm no more."
The Atlanta native also pointed to the rainbow imagery on his album cover and the lyrics of his song “C7osure (You Like)" as hints to his sexuality.
