Jon Cryer's ex-wife has accused the actor of making their son a subject of ridicule at school because his child support payments aren't enough to cover expensive holidays and parties. In 2011, the Two and a Half Men star was ordered to pay $8,000 (£5,000)-a-month to help his ex-wife Sarah Trigger cover the costs of bringing up their 13-year-old son Charlie Austin. Cryer tried to appeal against the decision, insisting Trigger only looked after their son four per cent of the time. However, she has now filed new papers for the amount to be increased - by a huge $80,000 (£53,333)-a-month. In documents, Trigger says Charlie is suffering because he can't keep up with his wealthy school friends who enjoy "exotic vacations in the summer and winter like Europe and Thailand". Trigger also claims the boy's classmates throw lavish parties and Bar Mitzvahs, the likes of which she can't afford to compete with on the amount Cryer gives her. The documents alleged Trigger needs the child support boost as she now looks after Charlie 50 per cent of the time. Cryer and his ex divorced in 2004. He married showbiz reporter Lisa Joyner in 2007, and went on to have a daughter, Daisy.
