Kym Marsh has opened up about all things Corrie, her appearance on Popstars and THAT weight jibe from ​Nigel Lythgoe​.

During a lengthy and at times emotional interview ​on Ireland's The Late Late Show, Marsh told Ryan Tubridy​ that it was hard to transition from Hear'Say to acting, because people don't take you seriously.

"Obviously I'm from a music background and it's not easy to break in to another industry when you're known for something else.

"But it's really hard to get someone to take you seriously especially when you've come from a reality show - and the one we were in was the first of it's kind, and everyone said 'It's Hearsay, they're so cheesy.'

"So it was kind of hard for me. But they took a chance on me and I'm so glad they did because it gave me the opportunity to show what I can do. And you're not in a show for ten years if you're no good."

She also spoke about 'hiding' her children during her appearance on PopStars​, something which people still go on about now.

She said: "You had to fill out this form and give details, age, where you live. They never asked me if I had children - so it wasn't a question that was ever asked.

"I'd experienced a lot of discrimination early before PopStars - lots would say 'She's got kids, she won't be reliable.' But the question was never asked so I never said.

"Then later down the line I told them and that was fine. Then they didn't confront me until much further down the line and confronted me for the tv show. But it was 'Well actually I told you ages ago.'"

Host Ryan Tubridy then asked her about Nigel Lythgoe's comments on her weight. The Popstars judge famously said: "Christmas is over and the goose has gotten fat."

Marsh said that while we're used to reality judges saying shocking things, no-one had really experienced that before Popstars.

"Our show was very much about making the band," she said. "And obviously we didn't know what was gonna happen. I was 24 years old away from my children and family, then to be filmed with someone saying you're fat when clearly I wasn't, was really harsh.

"I begged them not to put it out because I felt humiliated. I asked them not to and they said: "We're making a tv show."

Apparently Lythgoe did apologise to her, but "in the middle of the night when there were no cameras around".

"It had a huge effect on me as someone who suffered from an eating disorder at a young age," she continued. "I was size 12 at the time. It made me really unconfident and insecure about myself and the way that I looked. It didn't help."

Marsh also spoke about the loss of her son Archie at 22 weeks, explaining that it still hurts and you never get over it.

Marsh's appearance on ​The Late Late Show​ ​follows one on ​Good ​​​​Morning Britain​ in which she was lost for words during a fitness tracker giveaway.
