But did the superstar snub VIP meet and greet?

Beyonce attempted to make Princess Eugenie join her for a duet of her hit 'Irreplaceable' at her London O2 gig this week (30 April, 2013) - much to the horror of the young royal.

The star has started a six night string of shows at the O2, and Princess Eugenie was in attendance on Tuesday (29 April), as well as Matthew Williamson, Melissa Obadash, Patrick Cox, Donna Air and James Middleton.

Beyonce reportedly approached the crowd during the show and tried to get Princess Eugenie to sing "to the left, to the left," but apparently a friend stepped in and stopped her.

A source told the Mirror, "It was hilarious – Eugenie was on the front row with Kate Middleton’s brother, James, and his new girlfriend, Donna Air, plus designers Matthew Williamson and Patrick Cox. She was really excitable and filming the whole thing on her iPhone like any other fan."

They continued, "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."

However, it has also been claimed that Beyonce snubbed the Royal group, and failed to turn up to meet them as arranged for an official 'meet and greet'. The group were sat in the VIP section and had been promised the opportunity to meet Beyonce before the concert - but the 'Single Ladies' hitmaker did not show up.

A source told The Sun, "Matthew Williamson and the designers were really unhappy about the fact she failed to turn up. They had gone on the condition they were getting the money-can’t-buy experience. She didn’t show and there wasn’t an excuse."
