It was not only Kim Kardashian that went to see Beyonce in concert this week as Princess Eugenie decided she would like to go and see what all the fuss is about.

Eugenie attended the event with a couple of friends at London’s O2 arena on Tuesday as she had a really big shock as Beyonce stood at the end of the stage and spoke to the royal family member.

Just as Bey was strutting her suff around the stage  singing Irreplaceable and enlists members of the audience to SING “to the left, to the left” with her.

But it seem’s the Princess was one of them special people even if she didn’t want to be.

A insider has said:

“She was really excitable and filming the whole thing on her iPhone like any other fan.

Beyonce clearly didn’t recognise her so when it came to Irreplaceable, and the part where she picks on an audience member to join in with her, she simply chose the first woman she could reach.

When Eugenie, who had gone bright-red, ducked down, Beyonce was forced to quickly fill in the missing words and find a new, willing victim.

All Eugenie’s friends were teasing her about her stage fright for hours afterwards.”
