Chris Martin: Apple & Moses Help Test Out New Coldplay Music

Kids really do say the darndest things. Just ask Coldplay frontman Chris Martin, who admits that his toughest critics can often be his two children -- Apple, 8, and Moses, 6. That's what makes the them the perfect sounding boards for Martin's music.

The singer recently confessed to playing new Coldplay songs around the breakfast table for Apple and Moses and monitoring their reactions. "Kids are very honest -- if they start singing a song it's because they like it. It's a great gauge," Martin told The Sun.

Martin is currently touring with his band around the U.S., with Apple, Moses and Martin's wife, actress Gwyneth Paltrow, in tow. During Coldplay's June 29 show, Martin bolted from the stage and into the the audience to find his wife and give her a kiss, in what was a rare moment for the PDA-averse pair.
