What happened to 'America's Mayor'? 'Drunk' Giuliani imitates the Queen, denies hanging out with Prince Andrew and 'young girls', and calls top US general an 'ass***e' in unhinged rant during 9/11 commemoration dinner

Rudy Giuliani mocked Queen Elizabeth’s English accent, denied hanging out with Prince Andrew and underage women, and called America’s top military officer an ‘idiot’ and ‘a*****e’ during a 9/11 commemoration dinner in Manhattan on Saturday.

The former New York City mayor spoke at the Cipriani restaurant on Saturday, appearing at an annual dinner event to commemorate the September 11, 2001 terrorist attacks.

Giuliani's comments about Prince Andrew were made on the same day that lawyers for Virginia Giuffre said they served the British royal with legal papers. Giuffre alleges she was sexually assaulted by Prince Andrew - an allegation that he denies.

The rant on Saturday is just the latest bizarre public appearance by Giuliani - a once-beloved mayor who is credited with leading New York City out of the turmoil of the September 11, 2001 attacks but who has spiraled downward in recent years, raising questions about his sobriety and overall well-being. 

In February 2002, just months after the September 11 attacks, Giuliani was awarded an honorary knighthood by Queen Elizabeth II in recognition of his leadership during the tragedy. During Saturday's dinner, Giuliani tried to mimic the monarch.
