Richard King, a member of the Class of 2011, was on already suspended separation for previous conduct when the March 11 scrape happened at an airport in his hometown of Houston.
In a lawsuit against the Grammy Award-winning LaBelle, he says three of her bodyguards attacked him for no reason. The singer has countersued, saying King was drunk and hurling racial slurs.
Video shows King on the phone and a shoving match ensuing.
A lawyer for King didn't immediately return a call seeking comment.
West Point says the 23-year-old King will start classes Monday. If he meets academic standards, he will graduate in December.
