Robbie Williams sang 'Angels' ''five times'' at Princess Eugenie and Jack Brooksbank's wedding.

The royal couple tied the knot at St. George's Chapel at Windsor Castle last week, and the 44-year-old star gave an impromptu performance of his biggest hit at the wedding reception, hosted by Eugenie's parents Prince Andrew and Sarah Ferguson.

Speaking to the Daily Mirror newspaper, the 'Let Me Entertain You' hitmaker revealed: ''I did Angels five times.''

When asked if his wife Ayda Field joined in with his performance, he quipped: ''I don't think that would have been a gift to them. It would have been a punishment.''

Robbie and Ayda's six-year-old daughter Theodora - who they nickname Teddy - was a bridesmaid at the couple's nuptials, and her mother admitted she was ''nervous'' in case her little girl caused ''chaos'' in front of the Queen, but she was blown away with how well-behaved Teddy was.

She said: ''As a mum, you are nervous. Is she going to lose it? Is she going to cause chaos?

''Is there going to be a temper tantrum in front of the Queen?

''But she was amazing. I was so proud of her. She did such a great job. I had such a proud mummy moment.''

Teddy was joined by Eugenie's cousin Prince William and Duchess Catherine's daughter Princess Charlotte, Mia Tindall - daughter of Zara and Mike Tindall - Mia's cousins Savannah and Isla, Eugenie's goddaughter Maud Windsor in being bridesmaids.

Charlotte's brother, Prince George, was pageboy as was Louis de Givenchy, who is the son of the couple's friends.

The pair's marriage was watched by around 1,200 members of the public, who were selected by ballot to listen to a live broadcast in the castle grounds, whilst thousands more lined the streets of Windsor to watch the procession outside.

Guests - including Kate Moss, James Blunt, Ellie Goulding, Naomi Campbell, Cara and Poppy Delevingne and Liv Tyler - enjoyed tequila and pizza at their wedding reception.

The couple treated guests to a gourmet pizza truck and Casamigos margaritas. It is no surprise they opted for the tequila brand as Jack works as a brand manager for the company.

A series of receptions took place in the Waterloo Chamber, the Grand Reception Room and St. George's Hall in Windsor Castle, with finger foods - including Yorkshire pudding bites and miniature Scotch eggs - and Pol Roger champagne on offer.
