Britney Spears refuses to care about what others think of her decision to marry Kevin Federline after just three months of dating.

The TOXIC star fell in love with the dancer after claiming to have "kissed a lot of frogs" - and has compared her relationship with former beau JUSTIN TIMBERLAKE as "practice" for experiencing the real thing with Federline.

Spears, 22, says, "This is my life and I don't care what other people think. I love this guy.

"I knew the instant I met him that he was the one for me.

"I wish other people have what I have. I've kissed a lot of frogs in my life and now I have my prince. I've found my happily ever after.

"My other loves were like puppy dogs. They were practice for the real thing. I'm feeling everything. I'm excited. Elated. Happy."

Spears says of her 55-hour-long Las Vegas marriage to Jason Alexander earlier this year (04JAN04), "I had no idea it would become that big a deal. That thing was a total 'ugh'.

"I was not in love at all. It was my friend from home and we got crazy in Vegas. So marrying Kevin was the last thing I was thinking about doing.

"But then I said: 'You know what? This is my life and I don't care what people think.'

"I'm going to get married. I'm in love with him."
