Kimberly voiced her concern for Sarah, who has openly spoken about her battle with depression and booze, before praising her stint in the house so far as "great".
Sarah was prompted to reflect on her experience in the band after performing a rendition of the Girls Aloud hit The Promise in a CBB talent contest with X Factor finalist with Amelia Lily.
Speaking to Closer magazine about her boob-spiration, Jem explained: 'When I began glamour modelling, I was massively inspired by Katie and the way she looked, so I went for the biggest implants I could have'. She said she's been with Kanye West and Ashley Cole.
MailOnline have contacted Jemma Lucy's rep for comment.

But the singer, who allegedly bedded Danny Dyer, seemed to have better luck with the Big Brother ghouls than her housemates as she laughed at Derek's paranormal investigation.
Mob Wives star Marissa, who was voted out of the house on Tuesday night (08Aug17), told The Sun: "Sarah is a great girl".
Her fiery response online comes months after they were pictured in a series of hot and heavy PDAs earlier this year, fuelling speculation of a romance.
Showing off her colourful tattoos, Jemma glances seductively over her shoulder back at the camera, her bum and boobs visible from the side. "From a number of her underwear modelling shots, the upper breast fullness could have been caused with a good push-up bra or with breast implants", they then continued.
"Being around girls the whole time, it's hard some times, you know". I love the Adrenalin rush it gives me'.
"I've managed to watch a couple of episodes and it's actually really freakish seeing someone you know so well in there". I get Tweets from trolls saying I need a nose job, which can hurt, but I try not to let it get to me.
"I have tried to stay positive and they ask me what's wrong and I tell them".
