Luke deleted the cruel comments pretty quickly so no we're not sure exactly what he said, but based on Kelly's response, it looks like he was taking a nasty swipe at her weight.
"@luke_worrall you've made it very clear u only dated me 4 my life style but s*** tweets about me the day im @ a funeral u have hit a new low," Kelly fired back on Twitter.
"@luke_worrall it was fine when my Kellyphant ass was paying 4everything wasn't it? i just didn't think u could get much lower but u did #wow."
The 26-year-old then went on to ponder whether she should shut down her Twitter account all together: 'dont think i want a twitter page anymore the fact that ppl get joy from being mean 2 me makes me sick whats the point? there is to much evil," but supportive followers urged her to just block her ex instead.
Kelly later used Twitter to have a go at Aisleyne Horgan-Wallace, a former Big Brother UK contestant who gave an interview on morning TV about her friendship with Amy Winehouse.
"Any 'friend' of amy's talking 2 the press/tv are not her actual friend's. her real friends have more dignity then to get $ 2 talk about her!" tweeted Kelly.
