The source added: "They've been talking privately for a bit and hanging out."
Lovato was vocal about her interest in Johnson during his time on Hannah Brown's season of "The Bachelorette", and things heated up earlier this month when Johnson commented on her unedited bikini photo.
After Lovato shared the swimsuit photo alongside a powerful caption about appreciating one's body, Johnson commented: "Look at me like that again ? Love yaself."
In response, Lovato sent a flirty kiss and tongue-sticking-out emoji.
