Tulisa Contostavlos and Mark Wright have denied reports of of their fling in a set of furious Twitter messages.
The N-Dubz member and former The Only Way Is Essex star were alleged to have spent the night together at a hotel in Miami while Contostavlos was filming the video for her debut single.
The Sun (Sunday) claimed that sources said Wright is “head over heels” for the X Factor judge, while she was said to be “mortified” by the affair.
However, both stars have hit back at the story yesterday afternoon, with Contostavlos describing the allegations as “sick” and “disgusting”.
“I have sumthin 2 say 2day,” she started. “1.people make me sick the things they do 4 cash,disgustin.
2.why am I meant 2 b bangin every guy Im seen with (sic)?
“3.I have DEFFINITELY NOT shagged mark wright and I can swear that on my uncle B’s GRAVE!”
Contostavlos, who is believed to have separated from N-Dubz colleague Fazer in January, went on to reveal that she has in fact found love again.
“If the press r so bloody interested….In my love life!& their guna keep makin out I’m shaggin every bloke I meet till they have sumin 2 write about! GUESS WHAT…I am seeing some1!!cus Im a bloody human being.
“He is not mark wright!& 4 the record mark is not my type & nor me his…In fact he thinks Im a chick with a dick. & like my men a bit ruff around the edges!write that!middle finger is up.”
Wright, meanwhile, tweeted: “Funny how u cant even b friends with some1 in a group without people makin up rumours oh well another day another rumour #moveon enough said (sic).
“As 4 the people making up the rumours and selling lies on peoples personal life ur nothing but waste of air !! #lowlife #f***you…So easy 4 people 2 look at 2 people in public eye who have been seen 2 KNOW EACHOTHER & say “I no I’m going 2 earn some cash” 1 word #scum.
“Rant over !! So 2 sum it up I have not been with tulisa !! Annnddddd breathe !! Right let’s all have a lovely day now and move on from crap.”
The Sun quoted a source as saying: ‘It was a wild night and everybody was a bit worse for wear. Mark had been flirting with Tulisa all night and he really fancies her.’
The paper then alleged that Mark and Tulisa kissed and have been messaging since they both returned to the UK.
The pair were also romantically linked back in November, but Contostavlos again insisted the story was not true.
