Robbie Williams is giving up smoking to please his fiancee.

The 'Angels' singer has already cut his habit from 60 cigarettes to ten a day as he is keen to get healthier in order to start a family with actress Ayda Field.

A source told The Sun newspaper: "Ayda is very keen to start a family and knows the damage tobacco can do to sperm.

"It's hard for Robbie to say no to the woman he loves at the best of times. But it's even harder when, far from nagging him about smoking, she gives practical support and offers to be there for him when he's finding it tough.

"He has promised Ayda he will crack it. Now it's just a matter of when he's ready."

Ayda has banned Robbie from smoking cigarettes inside their Los Angeles mansion in a bid to make him reduce his habit even more.

The 30-year-old actress has also hired a personal trainer to help the 36-year-old pop star get in top shape before their wedding.

A source said: "Robbie is training hard. He is enjoying it and wants to do Ayda proud. She's putting pressure on him to shape up and set a wedding date."

Robbie recently admitted Ayda has been working hard to convince him to start a family.

Speaking about the possibility of having a baby, Robbie said: "I'm feeling good things. She keeps going on about it and really, really wants one - and I'm coming around to the idea. But it's slowly, slowly catchy monkey."
