Speaking in Jesy’s BBC documentary Odd One Out Chris says: “When I first started spending more time with her, especially staying around her house, I noticed that she had many insecurities and there were times where she wouldn’t let me see her physically without makeup.
“Especially the first four or five times where I’d come round and we’d go on dates and stuff.”
He adds: “She’d get up in the morning, almost before crack of dawn, to make sure she was out of bed and putting makeup on and she got back into bed with a full face of makeup on.
“I used to look at her and think she woke up like that, but she didn’t. She was pre-prepared and getting up in the morning.”
Chris also reveals how Jesy wouldn’t let him see her after a shower because she didn’t like her natural hair when it dries. The doting boyfriend keeps a picture of a makeup-free Jesy on his fridge and says of the photo: “I love it, because that is her, and that’s her with a fresh face”.
In another clip, Chris tells Jesy she shouldn’t feel self-conscious because she has a “glow” about her. He adds: “I think one day it will click and she’ll look at herself and she’ll see that she is beautiful, she’s unbelievable.
“She doesn’t see that when she takes her makeup off, that’s why I tell her every night.”
This comes after Chris was recently forced to defend his girlfriend after a cruel troll called her “ugly” on his Instagram.
In Jesy’s documentary, which airs on Thursday 12 September, Jesy heartbreakingly reveals that she attempted suicide after being trolled relentlessly online.
She told of how in 2013, when Little Mix returned to The X Factor, she had slimmed down, but was at her “lowest point” because she continued to get abuse online. Jesy says she “felt that I physically couldn’t tolerate the pain any more”.
It’s since been revealed that Katie Hopkins was part of the torrent of abuse that Jesy received online which drove her to attempt suicide.
Katie Hopkins tweeted after Little Mix’s X Factor return in 2013: “Packet Mix have still got a chubber in their ranks. Less Little Mix. More Pick n Mix.”
Speaking in her documentary Odd One Out, Jesy says of the tweets: “All I remember at that time is [thinking] what’s the f**king point?
“I’ve starved myself for a week and I’m still getting called fat. I could be the skinniest girl in the world and this is never going to go away.”
The singer’s bandmates, family and management found out about the attempt, but “once it was spoke about it wasn’t ever spoken about again” and the star was ordered to take time off, but she was too “frightened” of drawing attention to herself to take a break.
The other Little Mix singers said they saw her transform from a “amazing funny girl” into a “broken doll” after attempting to take her own life. Little Mix’s Jade Thirwall told The Sun: “We just had to watch this amazing, funny girl become a bit like a broken doll. It was horrible.”
She added: “I remember feeling really angry. I wanted to just find every single person that had ever said anything horrible to her, look them in the eye and say, ‘Look what you’ve done to this girl’.
“Every single person that said something should have been held accountable for making her feel like that.”
And, Jesy’s mum, Janice White, has also revealed in the documentary she wished the Little Mix success never happened and she “lost her daughter”.
Speaking to cameras, Janie said: “I always say I wish it was back to normal. I wish I could have life as it was and have my funny little Jes back.
“I am so proud and when I watch her on stage I get excited. I’m the loudest cheerer in the crowd.
“But as much as I love all that, and people must think how can you say that, if I could have my Jes back as she was before I’d change it like that. Not have the X Factor or any of that. Because I miss her.”
