The 'Me and My Broken Heart' hitmaker is comfortable in his own skin and is happy to stroll around the family home in his birthday suit, something his prudish mother is envious of.
Coleen, 51, admits she feels too embarrassed to be in the nude at home even if she's just there with her husband Ray Fensome or her 15-year-old daughter Ciara.
Speaking during a discussion about female body hang-ups on ITV daytime show 'Loose Women' on Tuesday (18.10.16), she said: "If I'm at the doctors, I'll just get undressed cause I think that's it their job and they see it all the time ... but at home I feel uncomfortable even if I'm just at home with Ciara.
"I don't where Jake gets it from - he can't be mine - he just doesn't get the whole thing like, 'Ooh, I'm naked, I'm naked.' He's just fine with it, I really admire that."
Coleen - who also has 27-year-old son Shane Roche Jr., whose dad, like Jake, is 'EastEnders' actor Shane Richie - also used her appearance as a panellist on the programme to defend 24-year-old Jake's fiancée Jesy Nelson from criticism her performance with her group Little Mix on 'The X Factor' was too sexy for younger viewers.
Jesy and her bandmates - Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall - were lambasted by some social media users for the booty-baring bodysuits they wore when they debuted their new single 'Shout Out To My Ex' on the TV talent show on Sunday night (16.10.16) but Coleen insists they looked great and have the right to wear what they want as "confident" young women.
She said: "I mean really, they had kind of swimsuits on, they didn't have their boobs out, they weren't showing anything you hadn't seen before. What people forget about Little Mix is that when they first came out they were this very sweet girl band, all very innocent and it was little kids who followed them and then over the years, as you do, you develop as a woman, you experience life more, you get more confident. What I like about them is that they go out there and they're so confident in themselves and for young girls who might have body image issues they go out there and they're all different shapes and sizes and they go, 'yeah, this is me'. I've seen a lot worse, no one says anything when Beyonce comes out in the same stuff.
Although I am bias because they are talking about my future daughter-in-law, I am very protective!"
