The Queen is reportedly in good spirits despite missing the Epsom Derby, an attendee claims to have been told by Duchess Kate.
Her Majesty was seen on the balcony with members of the Royal Family during the Trooping of the Colour on Thursday.
But the Queen was forced to miss the Service of Thanksgiving at St Paul's Cathedral yesterday.
She will also miss her beloved Epsom Derby today, watching the horse racing at home on tv.

But an attendee claimed to have asked Kate Middleton about Her Majesty's health, and got some good news.
Gill Smallwood claims Kate told her: "She was fine, it was just very tiring yesterday, and she had had a lovely, lovely time."
Kate also allegedly told her that her children George, Louis and Charlotte enjoyed the day.
Ms Smallwood, chief executive of domestic violence charity Fortalice, was made an MBE in the New Year honours and was among those invited to the St Paul’s service and a reception at the Guildhall afterwards.

She said it had been a “real honour” to be at the service and described it as “absolutely beautiful”.
Asked about the Queen, Ms Smallwood said: “She has just worked so hard for this country and it’s just a real honour to be here today.”
In a statement on Thursday, Buckingham Palace said the Queen “greatly enjoyed” her birthday parade and flypast in London but “did experience some discomfort”.
The palace said that, considering the “journey and activity required to participate” in the St Paul’s service, the Queen had “with great reluctance” concluded that she would not attend.
The monarch did attend a beacon lighting event at Windsor Castle on Thursday evening.
