But he quickly changed his mind and the couple announced their engagement.      

Britney told the People magazine: "I've found my happily ever after. This is my life and I don't care what people think. I love this guy.      

"I'm feeling everything. I'm excited. Elated. Happy."      

She also reveals that she wants children: "I definitely want to have some kids. I see myself with four or five. We're starting with a dog.      

"I just got a Maltese named Lucy."      

Britney met dancer Federline at a nightclub shortly after she broke up her marriage to childhood sweetheart Jason Alexander.
