Natasha Hamilton insists her relationship with her new fiance is ''different'' to any other she's had.

The Atomic Kitten singer - who has sons Josh, 14, Harry, 11, and Alfie, six, as well as two-year-old daughter Ella from four different relationships - revealed last week she had got engaged for the third time after Charles Day popped the question eight months into their relationship, and she believes this romance is her best yet.

Natasha - who has only been married once, to Riad Erraji - said: ''I've loved every man I've been in a serious relationship with but everything is different with Charlie.

''That's why we're engaged.

''We have such a special bond. We have a very mature relationship - there are no silly squabbles or bickering.''

And the 34-year-old beauty insists there is nothing ''weird'' about her personal life and she won't let other people's opinions stop her from being happy.

She said: ''People say I'm always falling in love but I've never been the type of person to be in a relationship with someone I'm not in love with.

''I don't think it's weird to have loved more than one man.

''I know it's quick, but what Charlie and I have is very special. Charlie is a great man, who loves me and is great with my children.

''I'm not going to let the opportunity to be happy pass me by for fear that people will judge me.''

Charles proposed to Natasha during a break in New York and she had no idea what was going to happen when he took her for drinks at the Empire Hotel.

She told Britain's OK! magazine: ''My jaw dropped and I started crying like a baby, I was so happy.

''We had spoken about wanting to get married at some point in the future, but I had no idea he was going to propose.

''About an hour before he proposed, he kept giggling to himself.

''At the time I couldn't work out why but now I know it is because he was nervous.''
