A fellow passenger told MailOnline: 'Patrick was very excited about the wedding.

'He was talking on the phone and chatting about the marriage arrangements with his wife throughout the flight.

'The couple held hands throughout the flight and were clearly feeling the love.'

Mr Adams and Ms Bellisario sat in the first class cabin for the nine-and-a-half hour United Airlines flight from Los Angeles LAX Airport to Heathrow.

The couple both brought their wedding outfits in the cabin to ensure they look their best at the Windsor Castle ceremony tomorrow afternoon.

'Patrick was carrying his outfit in a suit bag and his wife had her dress in a special carrier too,' the onlooker said.

Dressed in a black leather jacket and black baseball cap Mr Adams and his wife, who wore a Burberry rain jacket, wide-brimmed hat and jeans, were met by friends at they collected their luggage and whisked them out of Heathrow yesterday. 

Mr Adams and Ms Bellisario got straight into the party spirit, enjoying a 'traditional ale' at the Royal Standard of England pub, a few miles from the wedding venue in Windsor.
