In the public eye, Britney is a superstar and pop icon, but behind-closed-doors she’s just your chill southern girl, and her relationship with David Lucado reflects that.

“[To David] it is a regular relationship with a regular girl,” a source tells “He is pretty serious about it. I think they are in a really good place. It is going pretty well.”

Things are getting pretty heated between the two, who reportedly live together at her Thousand Oaks home.

“They are happy together,” the insider adds. “They are having a good time and enjoying the relationship. It’s more serious than most people think.”

The source added that despite keeping up with Britney’s busy schedule, David continues to work at his law firm job.
