Is there something in the Los Angeles water? Or is everyone in Hollywood just in a major hurry to have kids?

Rebecca Romjin, age 35, and Jerry O’Connell, age 34, are expecting twins.

The matched set will join the growing ranks of Celebrity Twinsets born to stars such as Marcia Cross, Angelina Jolie, Melissa Etheridge, Diana Krall, Holly Hunter, Jenifer Lopez, Patrick Dempsey, Sean Combs, Marcia Gay Harden, Dennis Quaid and Julia Roberts.

Gosh, expensive in vitro much? Is it a good idea for famous couples to do overnight express double duty?

Or should they do it the good old-fashioned natural way, one baby at a time? Your thoughts please.
