The 33-year-model, who shot to fame as the ‘six pack mum’ during her first pregnancy, revealed last month that she was still exercising twice a week to keep her energy levels up.



Looking much the same as she did with her first baby, Sarah has documented every stage of her second pregnancy – showing off her unbelievable belly, with many mums-to-be praising the inspiring posts.

“I'm pregnant too!! Just loving my new fitness journey while pregnant. You look great girl!!” said one.

“Amazing!! I'm 35 weeks and you have been such a huge inspiration to me!!” wrote another.
