HOLLYWOOD, CA—Lindsay Lohan has one. So does Meg Ryan. Jennifer Aniston is reportedly looking into getting one. And Brook Burns has three. What are these red hot celebrity accessories? Frozen embryos: portable fertilized egg cells that can be stored in a trendy Sub-Zero refrigeration unit or toted around town in a range of miniature carryalls.

Hollywood baby boom
In recent years, Hollywood has been caught up in a baby boom. America's sweetheart Julia Roberts is now the mother of twins, Gwyneth Paltrow has her very own apple, and everyone's favorite pop tart, Britney Spears, is scheduled to deliver a 'Baby Fed' this fall. And those actresses that aren't having babies of their own are importing them from other countries.

And embryo makes three
But not every starlet is ready to add an infant to her collection of Jimmy Choo shoes and Balenciaga bags. What's a girl to do? Finally there is an answer, say Hollywood insiders. A growing number of celebs are adopting pre-born babies: fertilized zygotes that are preserved in liquid nitrogen at a cool -196 degrees Celsius.

The coolest accessory
And while some shy celebs feel most comfortable leaving their embryos to chill in the privacy of their Hollywood homes, others are taking the cool cell clusters out on the town, tucked away in super-insulated bags, tiny pocketbooks, even lockets.

A little Nicole?
Reality star Nicole Richie has been spotted taking her "embryette" out for a spin at the uber-cool Tinsel Town night spot, Baked Potato. A source close to the actress and aspiring singer says that her decision to tote a zygote has nothing to do with politics. "She's proud of her genetic material and this is her way of saying 'watch out world. I've got something really special in her.'"

Wanted: eggs to go
While stars like Ms. Richie are brandishing their own frozen embryos, other actresses are flocking to super trendy Nightlight in search of zygotes. Actress Jennifer Love Hewitt was reportedly spotted zygote shopping at Nightlight last week, while American Idol winner Carrie Underwood is said to have placed several calls to the location, inquiring about embryo prices and features. Fave celeb shopping destination Kitson is even said to be thinking about adding a collection of frozen embryos and matching carrying cases to its fall and winter line up.

I'd like to thank
Celebrity watchers say that frozen embryos are already shaping up to be the must have accessory at this years award shows. "Last year everyone was wearing faux fur shrugs. This year you'll see a lot of miniature purses and lockets," predicts one stylist to the stars. "They're small but they're really well insulated to keep the contents cool."
