Thomas Rhett better move over, because it’s his little brother that fans are crushing on now.

The country star posted a video of his brother that he likely thought was innocent — his years-younger brother Tyler is heading to the beach in the clip, so he’s in swim trunks, but the point of posting is that he’s listening to Rhett’s hit song “Gone Country.”

“Rare sighting of my little brother listening to my music,” the singer writes in the caption.

But fans couldn’t help themselves:

“Soooo… he single?” one comment reads.

Others followed suit.

“Loving your brother- what a cutie!!!” says another.

By July, Rhett had caught on to what he’d done, sharing another photo of Tyler — this time a throwback that shows him holding Rhett’s two oldest daughters.

“Before I accidentally made Tyler a teenage heartthrob internet sensation, he was just my little brother,” Rhett writes alongside the picture. “Now he’s starring in the overdrive music vid.”

“Overdrive” is Rhett’s newest single, and Tyler Lankford is the music video’s star. According to his Instagram page, the teenager will be attending Western Kentucky University in the fall.

Tyler is the youngest of Rhett’s siblings — he also has a younger sister, Kasey Lee, who is 31. Rhett is 34 and will soon release his seventh studio album, About a Woman, on Aug. 23.
