Kate trying to get her marriage back on track

The supermodel has asked pals including Sadie Frost and her ex Jefferson Hack -- the father of her daughter Lila Grace -- to keep her company around the clock so she doesn't go back to her old party-hard habits.

A source told the Mail on Sunday newspaper: "It's all at Kate's request. She has loyal friends and she wants to be with them now.

"They are keeping her busy with wholesome activities such as brunches, lunches and holidays. She's not interested in clubbing."

Kate, 41, is said to still be wearing her wedding ring and will fly out to the United States in a bid to save her four-year marriage to The Kills rocker.

A source previously revealed: "They are going to meet up to really see if all is lost. They still care for each other. There have been several phone calls.

"Kate still wears her wedding ring and is desperate to see Jamie before his tour starts up again next month.

"She is not going to take no for an answer, and Jamie still cares about her. He knows they have a lot to sort out."
