Sir Paul McCartney has broken his silence over people who criticise his wife, Heather Mills McCartney.
The couple married in 2002
The former Beatle said he wanted to "set the record straight" in a message on his wife's website.
He joined Mills McCartney's sister, Fiona, in defending his wife against the "spiteful, nasty, personal and, untrue" stories by some journalists.
Mills McCartney has endured a barrage of press criticism and reports of family strife since they wed in 2002.
In the message, which was posted on the website late on Friday evening, Sir Paul appealed to the media to leave alone his 36-year-old second wife - who lost a leg in an horrific road crash in 1993.
Sir Paul wrote: "It hurts me to see her wounded by these scurrilous reports, and not have anyone to put the record straight."
He rubbished claims that the former model-turned landmines campaigner influences him on everything from hair dye and plastic surgery to the recent split with his long-time publicist Geoff Baker.
He said: "It is true that I colour my hair. Wow, shock horror! I've actually been doing this for many years now with varying degrees of success, but it's my hair, and if you don't like the result I'm afraid it's just too bad, but it's certainly nothing Heather suggested."
Sir Paul also dismissed reports of a family rift between Mills McCartney and his children, saying everyone gets on "great".
And he levelled criticism at those who accused Mills McCartney of being too possessive of him.
He added: "She was reported to always be clinging to me, the inference being that she was too possessive.

"Never mind the fact that I love her holding my arm, the real truth is that often the surface of a floor or pavement can be dangerous for an amputee to walk on, and a little help from a friend can sometimes be appreciated."
Sir Paul added that among the most shocking accusations he had read in the press was that "losing a leg was perhaps the best thing that ever happened to Heather as it fed her desire for self-publicity".
"Imagine losing a leg, and dealing with it as bravely as Heather has done and having to read that on top of it," he wrote.
Ms Mills, who is also Mills McCartney's manager, said the same press article prompted her to speak out on behalf of her sister.
She said: "This angered and disgusted me more than I can say - and is simply not something I can rise above.
"I was one of the few people who witnessed at first hand the pain my sister went through for months after her accident, never mind numerous other corrective operations over the years."
