Heather Mills envys Paul and Kylie

Melbourne (ANI): Heather Mills 'burst into tears" when she saw her estranged husband singing a sexy duet with pop princess Kylie Minogue on a New Year's Eve television special. Mills" pals have revealed that the animal rights activist was furious when she saw Minogue 'flirting" with the former Beatle and lying on top of a grand piano while singing his solo song, 'Dance Tonight", alongside Macca.

"She's really mad about the way Paul got close to Kylie. She reckons he did it on purpose and feels it was a deliberate public dig at her," News.com.au quoted one friend, as telling the Sunday Mirror. "She thinks he's just trying to prove a point, that he's moved on and is comfortable around other women. She was so hurt she burst into tears," the friend added. Sir Paul and Minogue appeared on BBC2 program, Jool's Holland annual 'Hootenanny," as special guests. When their duet ended, Sir Paul gave the Australian singer a big hug, lifting her off the ground.

"Heather was seething, seeing his flirting as an attempt to humiliate her. She thinks he's kidding himself if he thinks he'd stand a chance with Kylie anyway," another friend said. However, Macca"s friends said that he is an admirer of the way Kylie has coped with being diagnosed with breast cancer and returned to the public eye after recovering.

According to his friends, Minogue reminds Sir Paul of his former wife Linda, who expired nearly 10 years ago after her own struggle with cancer. "Paul really admires Kylie. He has an affinity with her. The way she coped with cancer with dignity reminds him of Linda. She's the complete opposite to Heather," the friend said.
