Whitney Houston got into an argument and was nearly kicked off of a Delta flight on Wednesday, October 12, when the singer refused to buckle her seatbelt.

Before the flight, which flew from Atlanta to Detroit, Houston argued with a flight attendant before she was eventually buckled up, People magazine reports. A source close to the singer told the magazine, "She wasn't drunk, drinking or on drugs; she was just exhausted."

Houston's publicist had no further comment on the incident.

In May, Houston, who has struggled with drug and alcohol abuse for years, relapsed and returned to rehab.

"Whitney Houston is currently in an out-patient rehab program for drug and alcohol treatment," the 48-year-old pop and R&B singer's spokesperson told People magazine at the time. "Whitney voluntarily entered the program to support her long-standing recovery process."

Houston, known for her songs in her 1992 film "The Bodyguard," including her cover of "I Will Always Love You," underwent treatment for substance abuse in 2004 and in 2005. Several years earlier, she told ABC News' Diane Sawyer in an interview that would spur a slew of online and late-night jokes: "Crack is cheap. We don't do crack. Crack is whack."

Houston told Sawyer that she has used alcohol, marijuana, cocaine and prescription drugs at different points during her career.

"I partied a lot," she said. " Trust me, I partied my tail off. You get to a point where you know the party's over."

In 2000, the singer was detained at a Hawaii airport after a security guard said some 15 grams of marijuana were found in her purse. The drug possession charge was later dismissed.
