Spotted: Kate Middleton was in tears at Prince Charlotte's dress fitting for Meghan Markle's wedding

Kate Middleton was reduced to tears during a dress-fitting just before the wedding of Prince Harry and Meghan Markle, it's been reported. 

When the world watched the royal wedding, it looked like it was full of love, but now news has emerged that the relationship between Meghan and Kate Middleton was rocky.

Just as the Duke and Duchess of Sussex move away from Wills and Kate's Kensington residence for a new life in Windsor, a report has emerged that Catherine was “left in tears” after a fitting for Princess Charlotte‘s flower girl dress.

A source told veteran royal reporter Camilla Tominey of The Daily Telegraph, “Kate had only just given birth to Prince Louis and was feeling quite emotional” — although just what upset her is unclear. 

Several insiders have told PEOPLE that there was a notable amount of “stress” surrounding those involved in the wedding, unsurprising given the fact the Meghan's own father Thomas Markle pulled out of the wedding five days before he was due to walk her down the aisle.

Kate, 36, and Meghan, 37, have made several joint appearances as part of the Royal Fab Four - plus their iconic venture to Wimbledon for a girls’ day.

But it is said they’re “very different women, despite their similar circumstances,” a source told The Daily Telegraph. “Meghan is an extrovert, whereas Kate is quite shy.”
