Susan Sarandon isnt one to blend in.

The 71-year-old actress may have committed a faux pas when she greeted Queen Elizabeth without an introduction over the weekend. Royal protocol dictates that guests should be presented to the queen before addressing her, according to outlets .

But whats to keep an enthusiastic Yank from saying hello with a handshake? The 92-year-old monarch didnt appear offended.

The Oscar winner was attending the Royal Windsor Cup polo match in Egham, England, on Sunday when she approached the monarch.

She got a smile from the queen, photos show in the ET segment above.

Maybe theyll meet again.
