Talk about an immaculate (looking) conception.

Professional hottie Karolina Kurkova just announced she's with child, putting her in good company with three other Victoria's Secret Angels who have all recently become pregnant.

In April, Heidi Klum announced her pregnancy, followed by Adriana Lima in May and Gisele Bündchen in June.

Who's the daddy? Kurkova's fiancé, filmmaker (and ex-marine) Archie Drury. Her publicist says they've been together for just over one year.

With Klum and Bündchen no longer walking the lingerie giant's runway, and Lima and Kurkova likely out of this year's Victoria's Secret Fashion Show, we're wondering who will step in to fill their shoes (or more accurately, wings).

And during the models' downtime, which hot-bodied, stylish mom-to-be will be the first to launch a full-blown line of sexy maternity lingerie -- not just nursing bras?

Come to think of it, maybe it will be Victoria's Secret. With this baby boom, they've got a built-in audience and supermodels on contract to boot. Not a bad idea. And you heard it here first!
