Singer Chris Martin charges own kids for performing

London: Singer Chris Martin is so worried about spoiling his kids - Apple and Moses - that he refuses to perform for free even at their birthday parties.

"We are too expensive for our kids` parties. We cost about 50 pounds for an hour, and we don`t give them any pocket money. Until they can afford it, we won`t play for them," thesun.co.uk quoted Martin as saying. Martin, and his wife, actress Gwyneth Paltrow don`t even give their children pocket money. IANS
