Jack Tweed and Chanelle Hayes dated for three months before splitting in July 2010

Jack Tweed claims that Chanelle Hayes never told him she was expecting a baby when they first started dating .

Jade Goody's widower says his mother told him that Chanelle, 22, was preggers before she did.

‘I told my mum where I was going and she said she thought Chanelle was pregnant,' he says.

‘I was like: "I don't know, she hasn't told me that!"'

Jack found it hard to believe that the former Big Brother contestant really was having ex Matthew Bates' child.

‘She didn't look pregnant so I didn't feel like she was pregnant!' he explains.

Jack also insists that he didn't cheat on Chanelle.

‘I definitely didn't [cheat]. I don't do things like that. I'm a good boy.'

Jack dated Chanelle from April 2010 until their split earlier this month.
