Robbie Williams warned about girlfriend by dad

London: Robbie Williams was warned by his father that fiancee Ayda Fields would be "trouble" as it was the singer`s first relationship where there was nothing to run away from.

The 36-year-old singer, who has been dating the actress for three years, was told by his dad Pete Conway that the American beauty was so right for him, he would struggle to find a reason to end their romance the way he had done with previous girlfriends, Daily Star reported.

"My dad met her and as he was leaving he turned to me and said, `You`re in trouble there, son` - as there was no reason to bolt," Williams said.

"After a while I just saw what was there - a massive-hearted, lovely human being who wants to take care of me and I want to do the same for her," he added.

The `Bodies` hitmaker also confirmed he knew Ayda was the one when he wrote a song about her.

"In my song `Won`t Do That To You`, I call her, `My Swiss army girlfriend, my Swiss army wife.` The moment I sang that in the studio was the moment I committed myself to the relationship. I went into the recording booth a singleton and came out in a committed relationship with somebody I`m going to marry," Williams added.
