Chris Martin has experimented with "alcohol and drugs".

Despite being known for his healthy and clean cut lifestyle, the Coldplay frontman insists he and his bandmates have lived The Rock 'n' roll lifestyle and partied hard.

He said: "Success and fame, alcohol and drugs. We've been through all of those things. They're just pitfalls, and that comes from a lot of travelling and a lot of down time."

The 34-year-old musician - who has just released the band's fifth LP 'Mylo Xyloto' - also revealed he feels blessed to be married to Gwyneth Paltrow and joked it's not bad "coming home to an Oscar winner".

Speaking about his relationship, Chris - who has two children, daughter Apple, seven, and five-year-old son Moses, with the actress - added: "It's not all bad. As you get older, you have kids, but there is also a lot more sadness. Our music is reflecting that."

When the band is on tour, the 'Paradise' singer insists he and his three bandmates - guitarist Jonny Buckland, bassist Guy Berryman and drummer Will Champion - become each other's substitute family and their closeness is reflected in everything the group does.

During an interview on UK station Absolute Radio, he said: "We split our songwriting credits and everything we get, we split it equally. It means when One Of Us is having a hard time or a problem, then we all have the best interests of each other at heart."
