An Elton John concert, held as part of the Monte Carlo Sporting Summer Festival, was interrupted when two women began violently feuding in the audience.
"The two of them were each wearing what looked like 70 carats of diamonds and ball gowns that looked equally expensive," one witness told the New York Post.
The brawl appears to have erupted when one party accused the other of blocking her view. A witness said a 70-year-old and a much younger woman were involved.
"When (the) younger blonde turned around, (the 70 year old) grabbed her hair and pulled out a gigantic blonde weave."
The witness said the two "ladies" slapped and kicked each other while still seated.
The violence quickly escalated and security guards were forced to intervene to stop them from slapping and kicking one another before escorting the females from the venue.
Playing in Monaco over five consecutive notes, John reportedly glanced at the two women and continued on with his performance of ‘Tiny Dancer’.
