From my vast knowledge of Paris Hilton’s psyche gleaned from reading her Hello Kitty journals and love letters found in her storage unit, I would say she has the emotional maturity of a high school freshman. She may have matured slightly since then, but if you listen to the simplistic hackneyed way she describes her latest relationship, it’s doubtful.

In a love book Paris filled out for Tommy Hillfiger model Jason Shaw, whom she dated from mid 2002 to 2003, and was engaged to briefly, she signed off “I love you forever & every & ever. Love always, your future wife and partner for life. Paris.”

Paris was 21 at the time, so while she was young it’s not like she was a teenager. A lot of young people say “forever” in relationships when they’re both gung ho, but it seems especially stupid to talk to the press about your marriage plans when you’re famous and have been dating for a short time. It’s not as stupid as actually getting married after a few weeks, though, so at least Paris is still slightly ahead of Mariah.

Paris, now 27, says that her boyfriend of not even three months, Benji Madden, wants to get married and that they talk about it. She even has her wedding dress planned:

“He wants to [get hitched],” she told PEOPLE Thursday night at London’s Nobu, where she showed up for a late-night snack with Madden and her parents. “We talk about it.”

In fact, she’s already pondering her gown: “I’d wear a beautiful white dress,” she said dreamily, “probably Dolce & Gabbana.”

The heiress, who is in town promoting her new fragrance, Can Can, couldn’t stop gushing about her new beau.

“We are the perfect match,” said the 27-year-old (who begins filming her MTV reality show, I Wanna Be Paris’s New Best Friend! on Monday). “We don’t like being apart, we like to stay with each other as much as we can.”

Nicole Richie and her baby’s father Joel Madden have been together over a year and a half and have a baby together. They’re engaged but aren’t in any hurry to get married. Paris and Joel’s twin Benji seem like they’re in a rush to the altar though. At least they’re not trying to keep up with Nicole and Joel in the baby department – as far as we know.

While Victoria Beckham was promoting her overpriced jeans at Harrods in London yesterday Paris Hilton had staged a photo op at the same time for her fragrance, Can Can. Victoria won the battle of the spokeswhores and most of the photographers flocked to her instead of Paris.
