STACEY Solomon was worried she now has a "giant vagina" as she opens up about the birth of her youngest son Rex.

The Loose Women panellist, 30, also shared a video of the moments just after the baby was born, as he lay crying on her stomach.

On her new podcast, Here We Go Again, the singer feared her vagina was too big when her midwife, Tamsin, said the baby plopped out after the head was through.

Tamsin says: "Once his head was out, the rest of him just followed."

Stacey then asks: "Is that because I've got a massive noony now?"

However, her midwife reassures: "Absolutely not, I promise you. When you've had a baby before, your first baby paves the way.

"Because your vagina goes back the way it was before. But your vagina is a muscle, you have muscle memory, so once the first baby has paved the way, the second, third and other babies come a lot easier."

On her Instagram Story, she shared a clip of her cutting Rex's umbilical cord.

Then she shared a photo of boyfriend and dad of Rex, Joe Swash, 37, tapping on the wall to distract himself from her waters being broken.

The midwives asked her to relax despite the excruciating pain, but the sound of Joe's tapping made everything worse.

Stacey explained how "the devil" took over and she raged at her boyfriend.

Joe said: "I didn't know where to be, what to do, how to handle it. All these things were happening in front of me and I didn't know what to do."

Stacey gave birth to Rex in May, one month early.

She also has Leighton, 7, and Zachary, 11, from previous relationships, and Joe has Harry, 12, from a previous relationship.
