Disrespecting a Beatle is one thing, but having a go at OUR Kylie is just not on Heather.

Reports from the UK have revealed that Heather Mills, Paul McCartney’s estranged wife, is furious with Kylie Minogue for flirting with her 64 year old ex during a televised NYE show aired on Monday.

Mills believes the flirty pop princess was having a personal dig as she rolled about on a grand piano, waving her legs in the air like she just don’t care.

Mills was also pissed at McCartney for wishing her a Merry Christmas as he picked up their daughter for the holidays, which she says he did “in a sarcastic tone”.

Since the couple split last year, McCartney has been seen around town with a string of younger women, including Nancy Shevell and Rosanne Arquette.

Meanwhile, Mills has allegedly been linked to 70s star Jake the Peg, leading some critics to suggest she’s gold-digging yet again.
