The 'Good Morning Britain' presenter, her co-star Laura Tobin and 'Britain's Got Talent's Amanda Holden have all been found to have the ideal derriere, with research suggesting their bums are better than those of Kim Kardashian West and Beyonce.

Piers Morgan explained on the ITV show: "Amanda Holden and Susanna Reid have the world’s best bums and beat Kim Kardashian’s peachy posterior, according to the golden ratio. They have been found to have the perfect golden ratio for posteriors.

"Dr Riccardo Frati … he’s been analysing the bottoms of leading celebrities. Michelle Keegan and Laura Tobin also scored highly on the theory.

"It’s a system developed by the ancient Greeks to measure physical perfection."

Despite this, Piers pointed out that fellow 'Good Morning Britain' star Charlotte Hawkins was overlooked by the research.

He said: "All of them have come below Reid and Tobin, but the one I feel sorry in all of this is [Charlotte] Hawkins, who hasn’t got a look in.

"Nor has the pandemic pin-up [Dr Hilary]."

According to new research, the ideal shape requires a three-two-three ratio for the bottom, waist and breast.

But Susanna, 49, thinks her body shape has changed since the coronavirus lockdown, suggesting she's piled on some weight in recent months.

She explained: "That is really, really weird. I feel like that was a study done pre-lockdown because post-lockdown my proportions are less three-two-three and more six-five-six."

Meanwhile, Dr Hilary jokingly offered to give Susanna a second opinion on the results of the study.

He quipped: "As a doctor, I do feel like this finding should be peer reviewed and a second opinion required."

In response, Susanna said: "That’s not in the least bit sleazy, is it, Dr H?"
