Fergie's cheeky comment to Princess Beatrice at Royal Wedding, according to a lip reader

All eyes were definitely on Princess Eugenie at the Royal Wedding but mother-of-the bride Sarah 'Fergie' Ferguson certainly turned a few heads in her fitted emerald dress.

But while the Duchess of York looked fantastic in her mother-of-the-bride ensemble, the former Weight Watchers spokesperson wasn't quite comfortable.

According to lip reader, Tina Lannin, Fergie told older daughter, Princess Beatrice: "My stomach, can't hold my stomach in".

To which the Maid of Honour replied "mine is OK as I'm wearing a corset," leaving the giggling, according to Daily Mail.

The conversation took place as they sat in the pews at St George's Chapel waiting for the bride to arrive.

Fergie and Beatrice arrived moments before Prince Charles, then The Queen, who is always the last person to arrive before the bride.

However, it seems the mother-of-the-bride caused some confusion for Robbie Williams's daughter Theodora, who was a bridesmaid on the day.

A video captured the bridal party waving off the happy couple on the West Steps outside the chapel during which Teddy, as she's affectionately known, asks Fergie: "are you The Queen?"

"No," Fergie replied, as she continued getting the youngsters in order.

"Are you a Princess?" Teddy continued pressing.

"Yes," she responded, looking a little flummoxed by the whole thing.

Meanwhile, Ms Lannin also revealed that it was Princess Eugenie who initiated the kiss with her new husband on the West Steps, saying "let's kiss".

While she says Zara Tindall told Prince Harry and Meghan Markle before the nuptials began: "It's very quiet compared to the screaming at your wedding".
