In the ongoing war between James Kennedy and Vanderpump Rules castmate Jax Taylor, we have to give Jax a point for at least making it on his flight home from Hawaii.

Kennedy, 24, was booted from a Southwest flight from Las Vegas to Los Angeles on Monday for being "too drunk," a source tells ET. The SUR busboy-turned-Pump DJ was celebrating Memorial Day with co-star LaLa Kent at Rehab's pool party at the Hard Rock Hotel.

"He and LaLa were screaming at each other in the terminal," the source reveals. "It looked like a classic drunken fight between friends...I'm pretty sure it was LaLa telling James to get it together before getting on the plane."

We're told Kent was overheard yelling "I hate you!" at Kennedy, which, knowing DJ James Kennedy, he probably responded to by saying, "You're nothing, you're beneath me, I'm James Kennedy, babe." That last part is just a guess though.

The reality stars were joined by Kennedy's girlfriend, Miss Sonoma County 2016 Raquel Leviss. "Right before they closed the doors, the airline worker said James couldn't get on because he was too drunk," our source explains. "LaLa got on the plane and Raquel stayed back at the airport with James."

Before the incident, Kennedy posted plenty of party pics from Vegas to his Instagram, including a shot with fellow reality TV DJ, DJ Pauly D, and his girlfriend, Aubrey O'Day.

ET has reached out to Kennedy and his rep for comment, so far we have not heard back.

Meanwhile, SUR-vers Tom Sandoval and Ariana Madix recently paid a visit to ET and we had them hand out SUR-perlatives to their VPR castmates. Find out what they said in the video below!
