Britney Spears' recent vacation ended on a sour note when the singer was reprimanded for her in-flight behavior. According to sources, Spears lit a cigarette during a charter flight from Cabo San Lucas to Los Angeles, which is a violation of federal aviation regulations.

The move alarmed flight attendants on the plane, who insisted that Spears, 43, put out the cigarette. Regardless, authorities were contacted mid-flight. When the plane landed in LAX, Spears was met by authorities and warned about her in-flight conduct, and was then free to leave.

"This is not her first warning," a source tells PEOPLE exclusively. "She doesn't exactly follow the rules."

JSX, the public charter operator that Spears was aboard, has no comment regarding the incident, while a rep for Spears did not return a request for comment. TMZ was first to report the news.

Spears was under a conservatorship for 13 years following mental health concerns after a series of troubling incidents in the early 2000s. Her father Jamie served as the conservator of her estate. She successfully petitioned the court to terminate the conservatorship in November 2021.

Since the conservatorship ended, Spears has released her best-selling memoir, The Woman in Me. In the tell-all book, she spoke about her childhood, her relationship with Justin Timberlake, dancing with a snake during the 2001 MTV VMAs and other anecdotes about her life in the spotlight.
