She rose to fame as a glamour model where she was never shy showing off her incredible curves.

But Kelly Brook has now revealed that she has to be careful about any extra weight gain because it all goes straight to her 34FF boobs.

The star, 45, has told how that is the last thing she wants as she prepares to run the London Marathon later this year.

Kelly went from a size 12 to 16 in 2018 after moving back to the UK from LA but dropped the weight with the help of SlimFast for which she is a brand ambᴀssador. 

Amid her training she spoke about being careful over any weight gain as she already struggles with her ample ᴀssets.

She told Ok! Magazine: ‘I went on a 6km run yesterday and I have to wear these incredible sports bras and lube everything up so there’s no chafing!

‘So I’m just not comfortable being heavier, I’m too much of an active person. 

‘And also with hormones and getting older, your metabolism slows down, so you just have to be a bit more aware of what you’re eating and how you live.’

Last year during an appearance on Loose Women she explained: ‘I’ve been having a few back problems recently and I went to the doctor and he told me I needed to lose weight.

‘I was like, ‘really?’, and he said, ‘Yeah you know, you’ve put on quite a bit of weight, up here’, as that’s where I put it on, my boobs.

‘My bras were not supporting me and it’s completely thrown my back out, so now I’m literally training to try and lose weight off my boobs.’

She added: ‘I’m running, but I can’t find sports bras, so I’m actually just holding them while I run to keep them in place!

‘It is helping. My doctor said if I strengthen my core, it’ll be a bit better.’ 

‘People think they want to get a boob job, but I was born with them, but I’d love to be able to do sport, not worry about them sagging or having back problems. It’s excruciating.’

It comes after Kelly revealed she’s made her mind up on whether she wants to have children or not, after an ‘honest’ admission from her grandma.

The model and actress opened up on a comment that has stuck with her and changed her views on becoming a mother.

In an interview with The Mirror, Kelly revealed that she asked her grandma if she had any regrets in life – and was shocked by her frank answer, when she responded that her biggest one was having children. 

She said: ‘Then I thought, ‘Actually, I don’t think I want them,’ and hearing that somebody had regrets, and that I might not regret not having children, made me feel really happy about my choice.’

Kelly reflected on how not having children leaves her life more open to different possibilities and used being able to move between LA and the UK as an example.

It came after Kelly opened up about her ‘traumatic and devastating’ miscarriages in previous relationships. 

She revealed that her and her husband Jeremy Parisi are ‘childless by choice’ as she spoke about their marriage.

Kelly revealed that she looks at her and Jeremy’s ‘beautiful life’ and how they aren’t ‘burdened’ by the turmoil of trying to have children.

However she got candid about her experience in previous relationships, as she revealed the trauma of going through IVF or experiencing miscarriages.

‘I am actually childless by choice at the moment, it’s not something that we have considered and I don’t think that should be a taboo,’ she told The Sun on Sunday.

‘I have been through pregnancies and miscarriages and I know how traumatic and devastating they are on you and on your relationship, I have been down that road with previous partners and it is a lot.

‘I look at the beautiful life we have and how we don’t have the burden of that.’

Kelly said that while she sees how much happiness children bring her family, she also sees the stress that comes with.

And while her and Jeremy love family time and caring for their dog, travel is a huge part of their lives and having children is not on their list of priorities.

However at the time Kelly admitted that she wasn’t completely closed off to being a mum in the future – something she was yet to discuss with her husband.

The couple revealed they want to become TV’s new power couple and believe their constant bickering makes them more ‘relatable.’

Kelly criticised duos who force their on-screen relationship and ‘portray an unrealistic dynamic’ to audiences.

Speaking exclusively to MailOnline, the former actress insists she and Frenchman Jeremy, who she married in 2022, aren’t trying to be ‘perfect’, which sets them apart from existing TV partnerships.
