Kylie Minogue will celebrate her 40th birthday next year with a massive world tour.

The '2 Hearts' singer - who has overcome breast cancer - has started working on ideas for the shows, which will kick off just days after she reaches the milestone age on May 28.

Kylie has teamed up with good friend and designer William Baker to ensure the concerts are as spectacular as possible.

William told Britain's The Sun newspaper: "I am so busy. I'm heading back into the studio with Kylie in February to start training for the tour we want to do in June.

"It's going to be fabulous. I have a couple of ideas but they need a bit of work. It takes ages to pull it all together so we want to take out time on it."

Kylie - who is set to release her first album in four years, 'X', in November - recently revealed she is cutting down on her workload to make her lifestyle healthier.

The star - who was given the all-clear from the disease early last year after having a partial mastectomy and a course of chemotherapy - said: "I've decided that from now on, I'd like to do working days. Like nine-to-five hours, no more working from 5am til 2am. Those are the main changes I've tried to make, because I can be my own worst enemy.

"I want to keep on finding my perfect harmony within my life and my work. And a family, yeah, that's something I'd love."
