Newly-single Mariah Carey, 44, recently took to the stage in a plunging corset and short mini skirt - something which seems to have offended Katie Hopkins.
Speaking about the performance, which saw the diva accidentally flash her knickers, Katie hinted that the curvy singer needs to lose weight - and even suggested that she join her on her own weight loss mission.
Sharing an unflattering image of Mariah mid-awkward wardrobe mishap, Katie tweeted: "Mariah darling, about this whole eat less move more thing. Wanna join?
"A gusset in the eye is a gusset too far."

Yikes. Unsurprisingly enough, many people have since slammed Katie for her comments.
One wrote: "Fat shaming in 2014? So passé."
"@KTHopkins you are criticising @MariahCarey... yet you was photographed/set up yourself bonking half naked I. A field now that's #classy NOT [sic]," commented another furiously.

Katie is in the process of trying to lose the extra pounds she gained for her TV show, Katie Hopkins Journey to Fat and Back.
After purposefully gorging on high-calorie ready meals, chocolate and sweets, Katie is now in the process of shedding the extra pounds, in a bid to prove that there are 'no excuses' for being overweight.
"It's all about eating less and moving more," she explained.
