Will the Queen be revealing her true colours ahead of the FA Cup Final when she attends the Royal Wedding between Prince Harry and Meghan Markle at Windsor Castle just hours earlier?

Betfred are 10/1 that the Monarch chooses a blue hat and that Chelsea win the FA Cup against Manchester United at Wembley.

And the patriotic bookie is a massive 40/1 that the Queen opts for a red double – a red hat and the Red Devils to lift the cup.

Green is favourite however at EVS, but Betfred have a special that both the Queen and Markle’s mum’s hat are both pink – which is proving a popular 20/1.

Betting on the colour of the hat has reached fever pitch but there are also hundreds wagering on whether Prince Harry will be clean shaven (6/5) or 8/13 that he will keep his trademark short beard.

Punters are also trying to hit the right note over which record will be their first dance…Whitney Houston tops the artists at 8/15, with Harry lookalike Ed Sheeran 9/4.

Elton John, who sang at Harry’s mothers funeral – Princess Diana, is odds-on to be in attendance – and Betfred are 3/1 that one of his songs gets the party started and 2/1 that he actually tinkles the ivories himself for the opening song.

With such a big date in the British sporting calendar, it’s key to note that Prince William is an avid Aston Villa fan, the Queen reportedly supports West Ham, whilst football fan Harry is thought to be a Gunner.

So whilst there’s plenty of speculation surrounding the wedding, one thing is for sure is there won’t be any family footy rows afterwards, whatever the Queen has ‘ON HER ‘EAD SON!’
