Tulisa and Dappy fight it out on Twitter
Dappy's lyrics include: ''I heard Simon Cowell thinks I'm a little w***er/ And that I'm getting on his t**s like cancer/ I don't want to start mentioning names (f**k it)/ Where they all now? They're bankrupt.
''Joe McElderry, oh what a stand up/ Alexandra [Burke], pull your socks up/ Where your hits at, you ain't no winner/ I feel bad cos your voice is amazing/ But your career is getting raped by a mason.''
And Tulisa, who's a judge on the show, isn't happy.
She Tweeted: ''Just puttin it out there. dont involve me in dappy's latest hype, I don't condone it in anyway. N its a shame I'm not around 2 control him (sic).''
Tulisa then made reference to Dappy's dad, Byron, who died in 2007: ''I told u hes a nut, I dealt wid this 4 13 years. I just hope people realise hes simply lost his mind since B's death. that's all, 4 his sake. (sic)''
The video for the track features a person wearing a Simon Cowell mask wrestling a person in an Alexandra Burke mask.
But Tulisa, 23, failed to see the funny side and told Dappy to 'sort it out'.
Dappy, 25, replied: ''T... Why would u say this about my work. Just so u can keep cool with your xf job. ''Sad really ... Guess im on my own again ... F**k x factor (sic).''
These two have a famously tumultuous relationship, but were believed to be friends again after they were pictured together recently.
We can't keep up! Family eh?
