On Thursday, Kate posed in black lingerie and asked her followers for advice on the skin pigmentation around her derriere.

Kate shared a selection of snaps showing off her pregnancy curves and pointing to areas around her posterior which have become darker in colour.

She penned: ‘Did anyone else get this during pregnancy? I only noticed when I was taking these photos. 

‘My skin looks like corned beef around my bum and top of thighs but then it stops and my legs are the same pale colour they always are.

‘The last photo if you swipe is where you can see the most. Anything I should be worried about or is it just my body doing strange things? Xx’

Kate has been very candid throughout her pregnancy and often updates fans on how she’s feeling as her due date approaches.

Earlier this month Kate shared her worries that Martin may not be able to attend the birth of their child due to rising Covid-19 cases.

The mum-to-be emotionally admitted in a video shared to her Instagram stories that she is ‘terrified’ at the thought of having to ‘go it alone’.

She explained that she was warned by her obstetrician that ‘there is a chance’ her partner might not be able to go to hospital with her amid the coronavirus crisis.

A teary-eyed Kate told her followers: ‘I’ve been crying, that’s why I look like death. 

‘So I’ve just got off the phone with my obstetrician, we were talking about the birth and my abdominal birth has been booked in, six weeks from today I’m going to have it.

‘But because of Covid cases on the rise there’s a chance that Boj might not be able to come to hospital with me and I might have to go it alone.’

She went on to explain that she has a ‘huge fear of childbirth’ and said she is ‘upset’ at the thought of welcoming her baby ‘without the person I love holding my hand’.

Kate continued: ‘So first of all, my heart goes out to any woman who’s had to give birth without their partner there.

‘As someone who has a huge fear of childbirth, the idea of giving birth to my baby alone without the person I love there holding my hand is just terrifying.

‘It’s just not for me, it’s not what I want. So of course I’m upset, but there’s nothing we can do.’

Kate scheduled an elective abdominal birth on the NHS due to her fear of spontaneous births.

The Big Brother star announced her pregnancy in September, two years after revealing her engagement to Martin.
