While Marnie wasn't trying to be nasty about Gemma or mock her about her size, she still received a bit of a backlash for commenting on Gemma's appearance.
The reality star had told her followers Gemma would look "unreal" if she slims down.
Taking to Twitter, Marnie tweeted: "Gemma Collins has actually got a really pretty face! If she lost weight I reckon she would be unreal. I've never noticed before #CBB."
Despite complimenting Gemma on her looks (albeit backhandedly), Marnie's post didn't sit well with fans.
One user hit back: "Someone's weight doesn't decide if they are pretty. If she's pretty, it's because she's pretty."
Another commented: "You're literally saying people have to be skinny to be good looking. I know a lot of bigger girls who are beautiful."
Many other Twitter users told Marnie they were "offended" by her comments and told the starlet to think before tweeting such things.
@MarnieGShore there is so much stupidity in this statement.. You can't be serious, so being a certain size is what makes someone pretty?— Gemma (@GemNicolee) January 22, 2016
@MarnieGShore you should think before you tweet love.— Èireann Jess (@eireannyes) January 22, 2016
@MarnieGShore hmm. I feel you're trying to be kind here, but it's a dangerous path to be saying women have to be slim to be attractive.— Martin Power (@M4Nightrider) January 22, 2016
@MarnieGShore what's her being over weight got anything to do with it!?!?— Amz (@Amygoo7) January 21, 2016
@MarnieGShore shouldn't be about losing weight marnie, I thought more of you than that— Faye Cairns (@qotob33) January 21, 2016
Marnie's tweet comes after Gemma has had to suffer a slew of cruel jibes about her weight lately.
On Celebrity Big Brother's Bit On The Side, Tina Malone shocked viewers with her comments on the former TOWIE star.
Referring to Gemma's meltdown over her hair extensions in the diary room, Tina said: "I think she should be more worried about getting a gastric band, maybe, than hair extensions. I think Gemma is really depressed because somebody has probably locked the fridge."
Gemma's official Twitter account hit back: "The weight comments well our girl got up designed an award winning clothing range & made plus size girls happy & what did you do-bullies."
Tina wasn't the only one to target Gemma's appearance, as some of the 34-year-old's housemates have done so too.
She faces eviction tonight along with six other celebrities: Megan McKenna, Stephanie Davis, Tiffany Pollard, John Partridge, Danniella Westbrook and Jeremy McConnell.
