Katherine Ryan has revealed she has undergone 'serious' cosmetic surgery on her face just eight weeks after welcoming her fourth child.

The comedian, 42, said that going under the knife so soon after giving birth to her daughter Holland with her husband Bobby Kootstra meant she had to pause breastfeeding.

Katherine also shares Fred, four, and Fenna, three, with fellow Canadian Bobby, and has a 16-year-old daughter, Violet, from a previous relationship.

'It was a lot. I will say this - it was better than I thought it would be,' Katherine said on her podcast, Telling Everybody Everything, on Monday.

'I went to York. There's an incredible surgeon there... a genius. This is controversial, but he is my ethnicity.'

She elaborated: 'I have really delicate features - I have a long face, I have a really narrow jawline. 

'I was not ever meant to have the Kylie Jenner heart-shaped jawline and these big Persian eyes. That was never going to work for me.

'This guy in York is like of a British, Irish background, his beautiful wife is Irish, and I want to look like her. 

'So I was like, I think this guy gets me... I think he gets what I'm going for.

'And he did some procedures on one of my friends who is so beautiful and youngish to be getting surgery. And I just loved his before and after gallery.'

She continued: 'It really matters, I think, to know someone real and to be able to see how their face moves, talk to them.

'You knew what they looked like before, you know what they look like after. That, to me, historically, has always been the push to get surgery.'

Katherine, who has openly discussed her interest in getting a face lift in recent months, did not disclose the procedure she underwent last Friday because it was filmed for a docuseries.

She added: 'I'm noticing a lot of Asian doctors or Persian doctors who have this idea, this aesthetic - take Dr. Simon Ourian, for example. He is the Beverley Hills injectables skin guy.

'He doesn't do surgery, that I know of, but he's the guy who appears sometimes in The Kardashians, and he does their injections.

'He's really talented, but I went to see him probably ten years ago... And I felt like I walked out of there looking a little more Kim Kardashian. 

\What each of us needs to do, I think, is stick as closely as possible to what mother nature intended.'

The star traced her recent cosmetic surgery decision back to her early twenties when she decided to have a breast augmentation.

‘When I started working at Hooters, I had no boobs at all,’ she recalled. 'I was like, I don't want to be a Hooters waitress with breast implants.

'A lot of the girls that I worked with had breast implants, nose jobs... And I thought a lot of the girls looked fake. 

'They had these bolted on titties, like the Playboy Mansion style boobs.

'But then a wonderful girl that I worked with called Kate got her breasts done, and they looked so lovely on her and so natural... that's when I made the decision to get breast implants.'

Katherine also admitted that she brought newborn Holland along for her latest cosmetic venture, which included a three-hour car ride last Thursday night from their home in north London.

‘I elected to take the baby with me because she just turned eight weeks that day. I'm still breastfeeding her, obviously, and I will be for a long time,’ she said.

'You can't breastfeed immediately after surgery, but I could obviously spend the night with her before and breastfeed her then, pump milk for the maternity nurse that I had, and then breastfeed her shortly thereafter and go home with her.'

She continued: 'I was thinking to myself after I got the surgery - which, wait till you see it, is pretty serious surgery - I was like, Katherine Ryan, what is your damage?

'Like, what exactly the f*** is wrong with you? Why have you brought a baby to surgery? 

'But then I thought, up and down this country, worldwide every day, we are giving women C-sections and then saying, sweet, go off and keep these twins alive.

'Women are expected to do so much - physically, emotionally, mentally. A C-section is a way more serious procedure than what I got. 

'They cut through, what is it, seven layers of tissue and fat and muscle, and then they give you a small person to keep alive.

'And even if you don't have a C section, if you give birth vaginally, there are a lot of women who have haemorrhoids, they have tears, they're in pain, they're exhausted.

'So what's this elective cosmetic procedure and looking after a newborn? It ain't nothing but a G thing is my official answer.'

Katherine, who said that she has experienced 'zero pain' from the procedure, said she hopes the footage of her recent cosmetic venture will hit screens in the near future.

'It has not yet been officially signed off, but it's been super fun to work with the crew,' she said. 

'I'm not the kind of person who would ever hide these things. Being honest is not for everyone. People have their own imprint of secrecy and shame and privacy and discretion. That's fine.

'But for me, I mean, can you imagine me doing something and not telling you? And that's why it baffles me when people are like, Katherine Ryan's had a nose job. No, if I had, I would tell you.'
