While all eyes were on Kate Middleton as she stepped out of a Rolls Royce to unveil her wedding dress to billions of people worldwide, there were likely quite a few men glancing at the woman with her -- her younger sister Pippa.
Pippa, 27, is apparently a well-known figure on the London social scene. But she was relatively unknown to the rest of the world -- that is, until she stepped out of the car wearing what the New York Daily News described as a "neckline-plunging, figure-hugging ivory dress."
People went atwitter on, well, Twitter. Here's a sampling:
Pippa Middleton is the most beautiful person I've ever seen in my life.
Anyone who doesn't have the hots for Pippa Middleton is insane..she is #fine.
Pippa Middleton, best body at the wedding other than David Beckham.
"Pippa has a reputation as being the really fun one, slightly louder and more outgoing than Kate," Tatler magazine editor Catherine Ostler told ABCNews.com. "Possibly slightly naughtier."
Pippa, short for Philippa, by the way, is considered one of the most eligible bachelorettes in the United Kingdom. However, she's not completely single -- she is dating former cricket star Alex Loudon.
