London - Princess Eugenie has revealed she is so excited to be marrying the love of her life today that she will be "running down the aisle".

In an interview on the eve of the royal wedding, the Queen’s granddaughter said she was nervous but couldn’t wait to exchange vows with drinks industry executive Jack Brooksbank, 32, because "it was love at first sight".

Eugenie, 28, the daughter of Prince Andrew and his ex-wife Sarah, Duchess of York, will marry her boyfriend of seven years at St George’s Chapel at Windsor Castle in a ceremony attended by most senior members of the Royal Family including Prince Philip.

The couple were at Windsor on Thursday for a wedding rehearsal. In an interview with This Morning presenters Eamonn Holmes and Ruth Langsford, they described the moment they first saw each other on ski holiday in Verbier, Switzerland.

Brooksbank said: "I saw you first, didn’t I? And we just stared at each other." Eugenie added: "Yes, and I thought, 'What a silly hat!'... and I thought, 'Who’s that?' and then you came over and shook my hand and I was all butterflies and nervous. I think I rang my mum that night and said, 'I’ve met this guy'..."

Brooksbank described his bride-to-be as a "bright shining light", while Eugenie said: "Jack’s the kind of guy, you know, when you’re lost at a party and you can’t find anyone to talk to, and you start panicking and you need help? He’ll walk in and make everyone feel so special. He’ll scoop you up and talk to you and make you feel a million dollars."

The couple said they immediately knew they wanted his brother Tom and her sister Princess Beatrice to be best man and maid of honour.

Eugenie said: "She’s my big sissy –I’ve looked up to her my whole life. I’ve wanted to be her at times... we’re best friends and I can’t think of anyone I’d want by my side more than her."
