Chris Martin charges own kids for performing

Singer Chris Martin is so worried about spoiling his kidsu00a0- Apple and Mosesu00a0- 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.
