Fiona Mills Sticks Up for Sister, Goes After Paul McCartney

It's still unclear if Heather Mills has received the divorce settlement we previously reported on.

But this much is apparent: Her sister may be as crazy as she is.

Indeed, Fiona Mills has launched a scathing attack on Paul McCartney and his alleged refusal to provide personal protection to his estranged wife and their daughter.

Fiona - who puts the good name of the princess in Shrek to shame - released a statement in which she claims her 39-year-old sister and niece Beatrice, 3, have received death threats - but have not been cared for like other members of the McCartney clan.

"The main reason that I am responding is that I am deeply concerned for the safety of my sister and her daughter," Fiona Mills writes on www.heathermills.org.

We assume she is yet to open a MySpace account is all.

"They are receiving death threats, not because she is getting a divorce, but because some of the British tabloids decided from day one that they wish to destroy her. ... Heather and Beatrice no longer receive the protection that would be afforded to any other member of the McCartney family facing such threats."

Maybe that's because Heather sucks. Or maybe the accusations toward Sir Paul aren't even true.

All we know is this: McCartney and Fiona should settle their differences like Anna Nicole Smith and Larry Birkhead. We'll even give the Beatles legend our Instant Messenger password if it'll help.
