'It's frankly embarrassing and complete lies...@KlassMyleene. I've stayed quiet for three years now but enough is enough. Please explain to me how I took your money?

'I lost so much money from our divorce and our house that we bought together.

'...and further money from me fighting you over letting me be a father to my kids whom I haven't seen in over a year..shameful

Angry: Graham has launched a Twitter rant in which he makes his feelings towards Myleene quite clear

'One day I hope you will put the interests of your children first and let them see their father.'Instead of focusing on what lies you can tell to boost your career.

Myleene no doubt angered her former spouse when she told MailOnline that she regrets signing him up as a joint director of a company which handled her estimated £11million assets.

'One of my girlfriends said later, “You married a former drug dealer who wouldn’t sign a prenup. What were you thinking?"

'I’ll never let that happen again, so help me God. If I’d decided to gamble with my money, I could take that, but someone taking it…. No.'

Myleene and Graham are parents to seven-year-old Ava and Hero, four. Myleene is thought to be single again after splitting from her mystery hunk back in May.

The former Hear'Say singer has not yet responded to Graham's tweets - MailOnline has contacted a spokesperson for both Myleene and Graham for further comment.
