Ananova:

Avril Lavigne pulled out of meeting Prince Charles at Capital FM's Party In The Park in London and threw organisers into a panic.

The Canadian rocker and R&B star Jamelia were due to sit either side of Charles as he watched the end of the show in aid of the Prince's Trust in Hyde Park.

But Lavigne apparently wasn't keen on meeting the Prince. An insider told The Sun: "She wanted to get away as soon as she completed her set. Hasty arrangements were made for Will Young to take Avril's place.

"The official line is that Avril had a plane to catch. But the truth is she is cripplingly shy and hates publicity stunts."

Earlier fans had been stopped from taking pictures and photographers were barred from snapping her as she walked on stage. She did a brief TV interview after her set but then left.

Meanwhile Jordan was banned from the celebrity line-up to meet Prince Charles because organisers feared she'd embarrass the festival's host, says The Sun.
