Sir Paul McCartney used Heather Mills' artificial leg to smuggle marijuana, actor Denis Leary has jokingly claimed.

The "Rescue Me" actor launched the attack against The Beatles legend and his ex-wife - who has an artificial leg following a motorcycle accident in 1993 - in his new book Why We Suck: A Feel-Good Guide to Staying Fat, Loud, Lazy and Stupid.

Heather Mills believes ice cream should be made from human breast milk. The 40-year-old former model is backing a campaign by PETA to make dessert company Ben and Jerry's replace cows' milk with the controversial substitute to lessen the suffering of animals on factory farms and improve people's health.

Tracy Reiman, PETA executive vice president, explained: "PETA's request comes after reports that a Swiss restaurant owner will begin purchasing breast milk from nursing mothers and substituting it for 75 per cent of the cows' milk in the food that he serves."

Melissa Joan Hart has "a little beef" with Heather Mills. The former "Sabrina, the Teenage Witch" star says she was approached to star in the first season of U.S. TV talent show "Dancing With The Stars," but was forced to turn it down because she was pregnant.

However, when she expressed interest in appearing in the fifth series of the program, Melissa says she was overlooked because bosses were so keen to get Sir Paul McCartney's ex-wife on the hit show.

Sir Paul McCartney attacks Heather Mills in a new song. "Nothing Too Much, Just Out Of Sight," sees the former Beatle screaming in an angry rant about his ex-wife, who received a $48 million settlement when their divorce was finalized earlier this year.

The track - which opens 'Electric Arguments', Paul's latest album with side-project The Fireman - features lyrics including "The last thing you do was try to betray me/ In new morning light I'll never forget it/ And that's just outta sight."

Heather Mills is "at peace" following her bitter divorce battle from Sir Paul McCartney. The 40-year-old charity campaigner - who received a $48 million settlement from the Beatles legend - is attempting to put her troubled year behind her and is concentrating on her charity work.

She said: "I'm in a really good place at the moment. I'm really at peace. I've spent a lot of time healing. It's been a very, very difficult time, the hardest ever, but I now want the chance to focus on charity and continue my work with the causes I really care about."

The Beatles legend, who has received death threats over his plans to perform in Israel for the country's 60th birthday celebrations tomorrow received a book from the Buddhist leader which gave him courage and hope.

Paul, who has been warned by Islamic extremist Omar Bakri "if he values his life" he should stay away, said: "I am reading a book - 'The Universe in a Single Atom' - that I have been sent by the Dalai Lama, which is comparing some Buddhist philosophy to modern quantum physics. Its quite striking that modern science has many things in common with some of the ancient religions. I think we are at a very interesting stage in human development and I just hope for the best and I am optimistic about it.
