Kate Middleton will be so nervous during her wedding to Prince William – she will be “screaming inside.”

Despite the stunning brunette’s calm exterior friends have claimed the royal bride is terrified about her nuptials on April 29.

Jessica Hay told Channel 5 documentary ‘The Princess and the Press: How Kate’s Life Will Change Forever’: “I think she’s going to be incredibly stressed on the day.

“Lot of emotions, very nervous, but she’ll keep very calm and cool and collected. I know what she’s like – she won’t show it but she’ll be screaming inside.

“There’s a lot of nervous laughter going on, I think obviously she’s nervous about what she’s getting herself into.”

Over one billion people worldwide will watch Kate and William, tie the knot at Westminster Abbey and Kate is said to be worried about making William proud and looking her best for the cameras.

Jessica said: “Obviously it’s very nerve-racking when you’re standing there and the cameras are going off all over the place.

“I think she was more worried about her eyes being closed in photographs. She just wanted to make Wills proud. She just wanted to be a nice fiancee.”

The Channel 5 documentary will be shown tonight in the UK at 8pm.
