"He wants to act almost like a father figure to Paris right now," the source explained, adding that he's taking a tough-love approach.
"He told her that her behavior is not going to fly anymore."
As RadarOnline.com previously reported, Paris, 20, boozed and fought with her boyfriend Gabriel Glenn during a wild weekend of partying in New Orleans for Mardi Gras. She had just checked out of rehab.
She vehemently denied anything serious had occurred, and was spotted at the movies with Gabriel later that day.
