Paris Hilton wants "three or four children" with boyfriend Benji Madden. The hotel heiress - who was introduced to her Good Charlotte rocker boyfriend when best friend Nicole Richie started dating Benji's twin Joel - is already planning her future with the musician, and thinks he would make a fantastic father.

She said: "I definitely want three or four children. And soon - maybe a year or two."

Lindsay Lohan and Paris Hilton are embroiled in a foul-mouthed internet fight. The pair - who were once friends - have been trading insults on popular social networking site Facebook.

"Mean Girls" star Lindsay branded the hotel heiress a "b***h" and "pathetic" before launching a four-letter tirade after Paris had set up a group on the site called "Firecrotch," referring to the actress' red hair.

Paris Hilton and Benji Madden's duets are "happy and fun." The hotel heiress - who has been dating Good Charlotte rocker Benji since early this year - has been recording tracks with her musician beau, and says the songs reflect the couple's relationship.

She said: "The songs are just being mixed right now and should be done soon. I've got a recording studio at my house in Los Angeles and so we've been working there every night. It's been fun. Our songs are just happy and fun dance music. It reflects what Benji and I are like together - happy and fun."

Paris Hilton and her boyfriend Benji Madden act like children to keep their "love young."

The socialite has revealed she enjoys visiting theme parks and amusement arcades with the Good Charlotte rocker because it ensures their relationship remains fun.
