Recent pictures of former X Factor contestant Stacey Solomon smoking during her pregnancy have led to criticism in the media.
The singer chose to address the issue live on ITV chat show Loose Women, via a telephone interview.
Asked by host Andrea McLean how she felt after seeing the photos in the papers, the singer replied: "It's something that I'm not proud of and something that I'm really struggling with in general.
"It's not just because everyone knows now, it's something that I don't want to do, and that I'm not happy that I'm doing. It's horrible"
Panel member Sherrie Hewson then asked Stacey if she had tried to give up the habit, to which she replied: "Yes, and that's an honest statement.
"I care more about my children than anything in the whole world, so obviously anything that I can do to give up means more to me than anything else."
