Gwyneth Paltrow's mother Blythe Danner has revealed she used to wear earplugs to son-in-law Chris Martin's gigs.

The 69-year-old Meet The Fockers star - who stars in new film The Lucky One with Zac Efron - told The Daily Mail she is a big Coldplay fan, but admitted she had to wear earplugs to watch them perform at first.

Blythe said: "I'm mostly a jazz fan and I've never really been into rock 'n' roll music - although I guess Coldplay isn't really rock 'n' roll - but he's made me a convert.

"I do go to their concerts whenever we're in the same town and I don't even have to wear earplugs any more, which I did in the beginning."

Her comments come as Chris Martin revealed that years of playing live has left him with tinnitus, a condition which can leave people with a buzzing or ringing in their ears, so he now protects his own ears when performing.

Blythe added she is a huge fan of her son-in-law and is pleased he has taught her grandchildren Apple, seven, and Moses, six, "good English manners".

She said: "Oh, Chris is wonderful and he's so good with their children.

"I wasn't there from the beginning of their relationship, but when I finally met him, I thought he was really wonderful.

"He wrote the song Fix You for Gwyneth when her father died and I weep every time I hear it."
