Celeb bump day: Kate Middleton, Carrie Underwood, Shakira, Rachel Bilson

Happy Wednesday Hump Day, also known to us as Celebrity Baby Bump Day. We have rounded up the cutest pregnant celebrities of the week, including Kate Middleton, who showed off her baby bump in a black Temperley London dress that you can buy too. Pregnant Carrie Underwood had many fans wondering where her baby bump went, while Shakira looked gorgeous in a sweet snapshot she shared. Pregnant Rachel Bilson and Blake Lively round out our list of the cutest baby bumps of the week.

Pregnant Kate Middleton looked gorgeous in this black and nude Temperley London emblem-sleeved dress at the Action on Addiction event in London last week. We love that Middleton is taking a bit more fashion risks during this pregnancy versus her more conservative looks when she was pregnant with Prince George.

The duchess, who is 13 weeks along, is feeling better and is finally able to make some appearances after dealing with extreme morning sickness. The palace recently announced her due date, revealing that Prince George, 15 months, will be expecting a little brother or sister in April.

Love her dress? You can actually buy exactly the same one. This chic black frock sold out overnight after Middleton was spotted in it, but it is now back in stock on the designer’s website. It is part of Temperley London’s pre-fall 2014 collection and sells for $675. We can’t say we are surprised it is a hot item, as this dress is perfect for holiday cocktail parties, regardless if you are pregnant or not.
