This weekend TV presenter and former X Factor contestant Stacey Solomon sparked outrage after she was caught lighting up just two months away from the birth of her second child.
The 22-year-old claimed she was "embarrassed" and is finding it difficult to quit. But it appears she's not alone. Even though smoking whilst pregant can cause serious health problems for babies and increase the risk of miscarriage and birth defects, it's estimated almost one in five expectant mums in the UK still carry on puffing. And for the under 20s, that figure rises to nearly half.
So why do mums-to-be struggle with kicking the habit? Well Stacey joins us now along with Dr Chris to share her story.
