Tom Cruise bowed to Katherine Jenkins after mistaking her for a member of the royal family

Speaking to the Telegraph newspaper, Katherine explained: "I ... met Tom Cruise at the Queen's Platinum Jubilee concert.

"The backstage was super tight - a thin corridor on both sides. I had on the most enormous Cinderella-style dress.

"As I was getting ready to go out on stage, Tom was walking off, being escorted on either side by military personnel. Because I do so much with the military, they knew me.

"They both bowed their heads and said "good evening ma'am" at which point, because there wasn't space, one of them pushed Tom out of my way and almost body-slammed him against the wall.

"I saw the confusion on his face but there was no time to stop and say hello."

Katherine revealed she later met the actor properly and she was convinced he'd mistaken her for a member of the Queen's family.

She said: "After the performance, when we did meet, he gave me a very strange handshake/nod/bow thing. Maybe he'd got confused and thought I was a royal?"

It comes after the soprano previously admitted she refuses to speak for a day before her gigs.

Katherine - who has children Aaliyah, eight, and six-year-old Xander with her husband of 10 years Andrew Levitas - won't utter a sound for 24 hours ahead of shows to preserve her voice - even if it means being unable to control her kids.

She told The Times newspaper: "I don't have alcohol, I drink loads of water and I stop going to noisy places so I don't overuse my voice. I want to stay focused.

"In the 24 hours before the show I won't speak at all. The voice is a muscle and when you whisper, you're still vibrating the cords and not getting the rest.

"I've got a six year old and an eight year old, and they find it hilarious that they can do whatever they like to mummy and I can't speak back, so the house becomes a big game of charades."
