Martha tells us that some women, like Grey's Anantomy star Katherine Heigl, consider not having babies because they don't want to gain weight. Not the case for others, like Ugly Betty mom-to-be Rebecca Romijn who has taken the plunge -- two baby girls are on the way -- and has, yes, definitely gained some weight and is feeling, well, something like a beached whale.

Says Rebecca for Page Six magazine (online this Monday): "I can't move anymore... I'm a beached whale! I have not been without a bra this entire pregnancy. I refuse. I'm not taking any chances. I'm determined to keep the puppies up!"

Weight gain is hard -- even if it for a blessed occasion like birthing a baby. But you know what? It's so worth it, especially when the weight melts away (it's possible with the right amount of diet and exercise, you know?) and the babies stick around for the long and happy haul. I think Rebecca will agree -- and for some reason, I get the feeling she'll whip that body (which doesn't happen to look much like a whale to me) right back into shape, just like these celebrities did.
