It used to be once a day when we got together but now we are at it like every other day . 'Things are fantastic between us in that department . I trust Mike completely and I know his womanising days are over . 'So what if he 's been married three times before but I know this time it is forever . We are crazy for each other . ' Mr Hopin , a former alcoholic of Ebbw Vale , South Wales , was strongly criticised after admitting he did n't even know the name of some of his 40 children .

She met the former fairground worker - whose favourite chat-up line is 'fancy a rump ? ' - a few weeks after meeting online . Mr Holpin pictured during an appearance on the TV show This Morning late last month . 'We had a cup of tea and a chat back at his place and he showed me pictures of his kids . He was open about his womanising past but he did n't tell me straightaway that he had around 40 kids . ' I have to admit I was stunned when he first told me but by then I was falling for him . ' They pair are now inseparable and spend their days watching horror films and going for long walks . After a year the couple moved in together and got engaged . Now the loved-up pair ca n't wait to tie the knot - the fourth time for Mr Holpin . Ms Morris said : ' I was overjoyed when he proposed but we have n't set a date yet . We 're saving £50 a month and it will a low key affair at a registry office . Of course we will invite all the kids but it 's up to them if they want to come . ' He has been accused of playing computer games for up to 20 hours a day but Ms Morris insists he is a model fiance . She said : 'Mike is on his computer a lot but he always helps me around the house . He mops the floors and chops the vegetables for dinner . ' Mr Holpin has been receiving benefits for 13 years and admits his £195 a week handouts on his 20-a-day smoking habit , as well as owning games consoles and widescreen TV 's . Ms Morris has n't worked since her 20 's due to suffering from bipolar disorder . 'Mike is an amazing dad and is always there for the kids . He is always around if they need to talk - that 's much more important than material goods . ' She added she ca n't wait to be the fourth Mrs Holpin , and said : 'People might think I am mad but I really do n't care . Mike is a new man and I know we are going to be together forever . '
