Robbie Williams is worried he will ''ruin'' his life in the next 18 months

The 'Candy' singer and his wife Ayda Field recently welcomed their first child into the world, daughter Theodora 'Teddy' Rose, and while he is enjoying his new ''stable'' home set-up, he admits he has an urge to ''ruin'' things and is worried he may do it at some point in the future.

Robbie - who has battled drink and drugs problems in the past - said: ''Where am I at now? On the Richter Scale ... being married to Ayda is amazing and it's sort of levelled the playing surface, and then having a kid. The house is full of love right now. Right now I'm on really good form, I've got an album that I'm really excited about and inevitably there will be a tour next year.

''I'm in a really, really good place. I'm happy and things are stable, and that's weird itself - I wan to ruin that, watch this space I probably will in the next 18 months.''

However, he is confident having a baby will stop him going too far.

He pondered: ''But I don't think I will, not with the baba.''

Robbie, 38, is now planning to permanently move back to his native UK from Los Angeles, as he feels he has fulfilled all his wishes there.

Speaking on British station BBC Radio 2, he said: ''I love my country; I love where I'm from - I hate the weather. Winter weather goes on until June ... but having said that, I want Teddy to have European sensibilities, English sensibilities, British sensibilities.

''(In LA) I learnt how to have a good time with relative anonymity. I went to Los Angeles and was surrounded by a bevy of beautiful women in the sunshine and I explored all my pop star wants and needs.''
