Swan told listeners of her shame and difficulty in giving up the addiction, of up to 5 cigarettes a week, while pregnant with her third child.
Swan had not told her partner, family or friends.
The confession follows a photographer snapping a photo of her in the act.
A statement has been released:
“Over the last year I have take up a habit I thought I kicked for good years ago, smoking the occasional cigarette, in total secret and never more than 5 a week.
“I never told the chippy or my friends I’d taken it up again and I’m not sure I ever would have come out of hiding and acknowledged I was addicted but this week a pap photographer snapped me smoking a cigarette whilst alone in my car and I knew it was only a matter of time before it became public.
“This week has been difficult and confronting on so many levels, but in many ways I am grateful I was caught in the act, it has forced me to come clean to those I love and to seek real solutions for me to kick it for good.
“I’m horrified that even though I know that smoking whilst pregnant is bad for my child, I couldn’t stop, I’d try but I couldn’t, telling myself just one can’t be too bad, knowing that it was. When you’re in denial you can justify anything.
“It’s made me realise that addiction is very real and not just something that happens to other people.
“I don’t have to go through this alone and am thankful for my wonderful family and friends who are supporting me through this.” Chrissie Swan
