Weighing a combined 251kg, England international rugby union stars (and brothers) Mako and Billy Vunipola are anything but twigs.
Let's just say, you wouldn't want to have either of these muscly New Zealand-born athletes running towards you anytime soon.
However, in a recent encounter with Her Majesty, the brothers were shocked to find the Monarch subtly imply they were a bit on the podgy side, much to their amusement.
Last night, the Queen celebrated the achievements of the Commonwealth at a Buckingham Palace reception and shook hands with the sportsmen.
Mako, who was part of the England team that beat Wales at the weekend in a Six Nations match, said of his encounter with HM to The Telegraph: '[The Queen] was saying that apparently rugby is getting a lot tougher now, everyone's fitter but she can't see it.'
His brother Billy jokingly added: 'I think she was calling us fat - which is fair enough.'
Far from being fat, the pair of England players are made of pure muscle, but we can understand the Queen's confusion.
I mean, just look at the size of her in comparison to the burly duo.
Of course, this isn't time the Queen has had people in hysterics over her comments about sport.
A 2015 book titled The Wicked Wit Of Queen Elizabeth by Karen Dolby details a story at Balmoral in which a member of staff once found the Queen jumping up and down with delight exclaiming, 'I've won, I've won!'.
Why?
Oh, she'd just heard that England's Test cricketers had defeated the Australians.
What a legend!
Last night's event saw the start of a series of major Commonwealth events this year, which culminate in a heads of government meeting for global leaders in London this April.
For the occasion, the Queen was joined by the Prince of Wales and Duchess of Cornwall, as well as Prince Philip and Prime Minister Theresa May
The Queen's appearance at the event came a day after the BBC claimed officials have been discussing who might succeed the Queen as head of the Commonwealth.
