Long before Kate Middleton could dream of becoming a royal style icon, there was Princess Diana -- one of the most elegant women to grace the British Monarchy.

And now, the late royal's memory will live on in the name of her brother's newest baby.

Earl Charles Spencer, Diana's only brother, welcomed baby Charlotte Diana Spencer into the world last week.

"We hadn't settled on a first name before the birth, but Charlotte is a name we both loved, and it really suits her. We knew as soon as we saw her," he told the U.K.'s Daily Mail. "I very much wanted her commemorated in the naming of our daughter."

Happy birthday, Charlotte Diana! And, congrats to the Earl and Countess Spencer from Team Glittarazzi.

DiD yOu KnOw? ... Princess Diana wasn't just a gorgeous woman with an affinity for charity work -- she was also a pretty cool lady. We're obsessed with reliving the moment when the Princess danced with John Travolta at a White House dinner in 1985.
