Paris Hilton launched her new hair extension line in New York yesterday - although she was noticeably lacking in actual hair extensions herself - and as well as wearing a really very pretty white dress, she was also sporting a diamond ring on that finger (sadly out of shot).

But when asked if her new bling was an engagement ring from Benji Madden, She told reporters: "No, it's just a present. He's sweet."

That said, Paris revealed that she and Benji have discussed marriage. Well, they have been dating for four months, you know. "We want to stay together forever," she gushes. "I wouldn't do a Vegas [wedding]. I don't know where or when but I do want it to be romantic."

She also said that she wants kids, is "Aunt Paris" to Nicole Richie's baby Harlow - and has "grown up" since dating Benji.

"When I was younger I loved to go out, but now that I'm in a really great relationship it's so much more fun to stay at home," she says, "We don't really like to go out. We have game night, friends come over and play Monopoly. It's chill."

It is, indeed, chill, Paris. Hang on a minute: does that mean it's not 'hot'?
