I couldn't possibly ignore the amazing pictures of Heidi Klum and her fantastic bump at the Emmy Awards in LA this week.

There are bumps, and then there are bumps! I guess there is no denying this one!

A few weeks away from the arrival of her fourth child (a girl), one can only applaud Ms Klum for looking so resplendent and putting her bump on show with such pride.

Of course, decked out in an expensive designer frock and with fabulous hair and make-up, most mums-to-be could probably look this good, but it's another matter as to whether we could summon up the energy to go out to a social event - and with the world's camera lenses following our every move as well. The poor girl probably just wanted to curl up on the sofa in something much more comfortable and have her feet rubbed! I'm guessing the floor length gown is hiding flat shoes and very swollen ankles!

Heidi was quoted as saying that she was delighted not to have to suck her tummy in for this red carpet appearance! Not that she has much of a tummy problem on a normal day at the office.

Anyway, good on ya Heidi. You're a great advert for displaying your bump with pride and with style!

There must have been a lot of twinkles in celebrities eyes over the last few months as this week we are delighted to hear of not one, not two, not three but four pregnancy announcements!

Winning the prize for the most modern way to share this news is Radio One DJ Sara Cox who announced that she is expecting her third child though latest social networking phenomenon, Twitter.

News travels impossibly fast on this virtual super-highway, so let's hope she got round to telling all the family and friends first!

Meanwhile, rumours that Brazilian beauty Gisele and husband Tom Brady are expecting a baby have finally been confirmed with the coupe announcing that their baby is due in December.

Next up, Irish actor Colin Farrell confirmed at the weekend that he is to become a father for the second time. The Dubliner, who starred in black comedy In Bruges, confirmed his actress girlfriend is expecting the couple's first baby.

And finally, England footballer Joe Cole and wife Carly Zucker who were married three months ago, have announced that their 'honeymoon baby' dreams have come true and they are expecting their first baby in six months. Ms Zucker is already sporting a tiny baby bump.

With all these yummy mummys in waiting, we can look forward to plenty more bump-envy in the months ahead, and who knows, if all these parents-to-be catch on to the Twitter craze, we can expect to hear a lot more of the pitter patter of tiny tweets!

As a mum to two fabulous but utterly exhausting boys, I am completely fascinated by (oh, alright, completely envious of) celebrity mums and their offspring.

I am constantly amazed by the style and glamour of heavily pregnant starlets who sashay down the red carpet radiating elegance in their towering Louboutins and designer frocks. We see endless images of celeb mums-to-be positively blooming and showing off their burgeoning baby bumps in true Hollywood style, while most of us are still suffering from morning sickness and unable to leave the house.

In recent weeks we have seen many snaps of Sarah Michelle Gellar looking expectantly fabulous at her baby shower and shopping in LA. Even more amazing are this week's pictures of Matthew McConaughey's girlfriend Camila Alves looking every inch the perfect mum-to-be as she strolls on the beach with her one year old son. It never ceases to amaze me how toned, resplendent and fabulous these ladies manage to look. Where, pray tell, are the swollen ankles? What about the stretch marks? Heartburn, anyone?

Should we look on with envy, or is this public parading of the bump actually a positive thing? Perhaps so. Too many mums-to-be (myself included) get all hung up about their bodies changing and putting on weight during pregnancy. We bemoan the fact that we can't find anything to wear for a night out with the girls and complain about not being able to paint our own toe nails.

Even though we may not all manage to pluck up the confidence to pose naked for a magazine cover, or stroll along the beach in a bikini when six months pregnant, maybe these ladies have a point. Pregnancy is an amazing thing and whatever your situation in life, and whatever the state of you body, it is undeniably something to be celebrated, enjoyed and hey, even flaunted to waiting camera lenses if the mood takes you!

So, here's to the glamorous bump brigade. Keep them coming ladies.
