Darlings, everyone who's anyone is flying to a Caribbean island to get married. Larry Page and Lucy Southworth did the deed on some spit of sand called Necker Island. Randi Zuckerberg?

We hear that friends of Randi Zuckerberg, better known as nerd chanteuse Randi Jayne, are surprising the Facebook marketer with a bachelorette party in Las Vegas this weekend. The place: the Hard Rock Hotel, where they've secured two suites. (Zuckerberg is set to wed Brent Tworetzky, an associate at Shasta Ventures, in May.) The bacchanalia's expected to last all weekend, including a dinner at Tao and a night out at Rain. Who's going?

Last seen bravely trying to block Julia Allison's path to a geek — her brother, Facebook CEO Mark Zuckerberg — Randi Zuckerberg will marry her college sweetheart, Brent Tworetzky, in May. Lucky guy.

You just saved me money on wedding invites! ;-)"
