The ex-girlriend of footballer Danny Simpson, who is rumoured to be dating X Factor judge Tulisa, claims that Simpson previously mocked the singer's sex tape.

Stephanie Ward earlier hit out at the 'Young' chart topper after she was said to have spent the night with Simpson, with Ward calling Tulisa a 'homewrecker'. Now, in a further attack on the singer, Ward claims her potential new beau laughed at her sex tape when it leaked earlier in 2012.

"Danny showed me the video on his phone as we sat on the sofa. I think one of the football lads sent it to him," said Ward in an interview with The Sun newspaper.

'We watched it together but it didn’t turn us on or anything - it was rubbish. I remember Dan laughing his head off.

'He said, "Oh my god she needs to work on her tekkers."

'Tekkers' is slang for 'technique', and ward is referring to oral sex.

"It's ironic to think that he didn’t think she was very good in the bedroom - and now he’s with her," added Ward.

"I'm totally confused to be honest because if Danny saw someone like Tulisa in a club he’d walk by," she continued. "It’s so upsetting as we only had sex with each other on Bonfire Night after having a lovely night at a firework display with Skye (the couple's 16-month old child)"

Tulisa pre-empted Ward's interview with the tabloid on Twitter, already aware on Friday (16 November, 2012), that Ward had spoken to The Sun.

Tulisa wrote on Twitter - in her unique 'text slang' style - "I av always kept it real n that aint about 2 change, u r a liar n a psychotic obsessed nutta!wait til I tell it how it is...wrongen."

She followed it up by adding, "I don't want 2 get in2 a public war of words, but what is being written about me 2moro is absolutely not true."
