The 25-year-old singer sacked her unnamed handlers and launched a furious tirade against them on the micro-blogging site, claiming she was overworked to the point of collapse.
Rebecca wrote: ''resorting to stalking my twitter the same people that watched me collapse ... And gave me a can of coke and said now go do your interview .
''The same people that worked me so much I collapsed and had to say stop!!! I need to see my children you need to give me time off vile!!!!
''Was so exhausted I couldn't physically walk on my own but was still told I had to work!!! âª#vile (sic).''
the qualified legal secretary added ''See you in court!!! âª#greedyvermon
''Be nice to have a nice new responsible caring management team!! Who care for me and my childrens well being âª#seeyouincourt!!! (sic).''
Rebecca has two kids and was clearly worried about the strain of juggling a hectic career and her family.
Neither Rebecca nor her management company have made any further comment on the claims.
