The X Factor judges let off some steam

Tulisa Contostavlos has admitted that she had to hide a number of drunken injuries on last weekend’s X Factor after enjoying a wild night out with Nicole Scherzinger.

The judges got a little crazy in raunchy costumes to celebrate contestant Rylan Clark‘s Halloween-themed 24th birthday at London club Mahiki last week.

‘I got hammered that night! I even fell over in the karaoke room,’ says Tulisa, 24.

‘I slipped and landed flat on my back. I’m covered in bruises.’

Tulisa had a falling out with Gary Barlow on Saturday night’s show after he complained about her ‘fag ash breath’ because she’d criticised his act Christopher Maloney‘s choice of song.

But she’s rubbished rumours that there’s also tension between her and former Pussycat Dolls singer Nicole, 34.

Nicole and I are party animals!’ Tulisa tells Metro.

‘We always have a wicked time when we go out together.’
