“They met in Nashville and Kacey is into him,” the source says. “She likes that he is a doctor and not very involved in the entertainment industry, but that he also gets it.”

The country crooner sparked romance rumors with the Nashville-based doctor on Monday, after posting a photo of them together on her Instagram Story.

The two were also spotted embracing each other in Los Angeles as they waited for an Uber to arrive on Sunday. The “Rainbow” singer can be seen keeping it casual in a blue-and-white, striped two-piece set while Onuoha wore a denim jacket and jeans.
