GEMMA Collins has left her co-stars on The Real Full Monty open-mouthed after revealing the weight of one of her boobs.
The self-confessed diva admitted to the girls on the ITV1 show that she had weighed her boobs one at a time on scales at home.
Gemma, 42, told them all that each of her boobs weighed 7lbs.
Sitting around a table, the former Towie star made the confession as the ladies prepared to have their breasts cast with plaster.
Gemma said: "I weighed my boobs once. They are 7lbs each.

"I just got the scales and put them on."
Looking shocked, Coronation Street legend Sherrie Hewson gasped: "That's 14lbs."
Later, Gemma was shown her breast cast for the first time and noticed that she is not symmetrical.
But accepting her natural body, she shrugged it off and said: "My right one is so much bigger than my left. Let's not be shy."
Gemma's co-stars - Sherrie, Loose Women star Coleen Nolan, Dancing On Ice's Vanessa Bauer and Corrie actress Victoria Ekanoye - all had their boobs cast by an artist.
They were then shown painting the casts with bright colours while talking about their own personal experiences with cancer.
Gemma opted to paint hers bright pink with glitter.
"I like my wonky right boob," she said, as she took a step back to admire her handiwork.
The new series of The Real Full Monty kicked off on Monday night.
TV presenter Julia Bradbury completes the female line up, but she had taken time away from filming to be with her young children on the boob casting day.

Meanwhile, there is a stellar lineup of men taking part in the show this year too.
Towie's Pete Wicks, former footballer and TV personality Ashley Cain, and rugby ace Ben Cohen will be getting their kit off.
They will also be joined on stage by former royal butler Paul Burrell and RuPaul Drag Race star Nick Collier, AKA Ella Vaday.
The Real Full Monty raises awareness of cancer and urges the public to get themselves checked regularly.
Viewers will watch as the famous faces put on a festive dance performance before throwing off their costumes.
They are taken through the process by Ashley Banjo, their choreographer, and for the first year, former participant Coleen Nolan, will work as a 'nudity mentor'.
- The Real Full Monty continues at 9pm, ITV1/ ITVX, Tuesday December 12
