Another supermodel has some BIG baby news

It's been a busy week for supermodel baby news; and now top mod Karolina Kurkova has joined the happy bunch expecting new additions, announcing her pregnancy on social media today. The Czech stunner, mum to five-year-old Tobin, posted the following message on Instagram: ‘My second bundle of joy is on its way :) and Tobin can't wait! #Happiness #Love #KKBaby2.’

The model, 31, named one of the world's "50 Most Beautiful People", married Archie Drury in 2009. The New York based couple are reportedly due at Christmas. Last week, Victoria's Secret "Angel" and Karolina's fellow supermodel, Anne V gave birth to a baby girl, Alaska. There must be something in the water at Fashion Week.
