Now, here’s a couple whose lives would make some amazing reality television.

Paris Hilton’s little sister, Nicky, is today in London to marry James Rothschild, one of the heirs of Europe’s last great banking family.

Nicky, who turned down the option of appearing in the The Simple Life reality-TV show that propelled her sister to fame, has pursued a career in fashion.

Nicky’s first wedding, to banker Todd Meister, took place in Las Vegas after a night out in August 2004. The only guests were Paris and actress Bijou Phillips. Within eight weeks, they had split

Oh, and Paris? She’s the bridesmaid (again) this time round.
