Heather Mills isn’t up to anything new, her former sister-in-law tells Inside Edition:

Dianna Karmal-Davies, whose brother Alfie Karmal married Mills in 1989, dubbed Mills a liar and a hypocrite. Dianna said accusations Mills leveled at Sir Paul McCartney during her recent television rants are the carbon copy of stories she made up about Alfie following their divorce in 1991.

But wait! There’s more! Could the animal-rights tabloid queen have a secret thing for mink?

Karmal also alleges that Mills has lied numerous times about the fact she used to wear fur. As proof Mills’ former friend showed footage of Mucca wearing a 42-pelt mink fur coat. “The fur was her mother’s coat. She loved the coat and so did Heather.”

Karmal-Davies said that although Mills claims she only wore the coat in memory of her mother who had died just days before, the story is a fabrication. “It was videotaped - she was wearing it at a friend’s wedding.”

Karmel-Davies said Mills’ mother passed in February, and the video was actually shot seven months later in September. “She actually fabricated and changed the date of her mother’s death.”

Bonus: Earlier this year, London’s Daily Mail chronicled some of Heather’s other fabrications. Guess who stopped being a vegetarian after the PETA-touting Sir Paul ditched her?
