When you're seven months pregnant and having trouble sleeping, probably the last thing you want to do is strap on a pair of six inch heels and schlep down the red carpet to parade in front of a bank of cameras.
But one advantage pregnant stars do have compared to us mere mortals is the ability to call on a clutch of top-end designers and stylists to dress their bumps. After all, if there's one gripe many pregnant women share, it's the lack of flattering and glamorous maternity fashion.
