Nicole Scherzinger has been accused of bad behaviour during her ten-month run on Broadway. The singer has been wowing crowds in both New York and London with her portrayal of Norma Desmond in the hit stage show, even winning a Tony Award for Best Performance by an Actress in a Leading Role in a Musical. However, behind the scenes Nicole has reportedly left bosses fuming. It has been alleged that Nicole had been offered to attend a session with a make-up artist on the day of the Tony Awards
