Sam Bailey has revealed that she is pregnant.

The X Factor 2013 winner, who already has two children, told The Sun that she found out about her new baby whilst her and husband Craig were shopping in a supermarket.

She said: "I went and did it in the toilet while he was getting all the food I came out and went, 'Yep - I'm pregnant'. It wasn't planned."

Bailey confirmed that her upcoming headline UK tour was shifted to next year as a result of the news, saying:

"When I got into the car I was really upset because I thought I'd let everyone at my management and the record label down. But they were really good about it. I was going to go on tour solo at the end of October - but I have to move it until January."

The singer has since uploaded a baby scan photo to Twitter along with the caption: "Hey everyone...... Meet peanut!!! :-)."

Bailey meanwhile is due to release her debut album 'The Power of Love' on March 24.
