The 'X Factor' 2013 winner, who is pregnant with her third child, took to her Twitter account today (16.04.14) to announce that she and her husband Craig will welcome another daughter into the world later this year.
She tweeted: "Me and Craig are proud to announce we are having a little girl... A special thank you to @miracleprogress xxxx (sic)."
However, it appears sam's five-year-old son Tommy was hoping for a baby brother rather than another sister.
Sam, 36, who also has eight-year-old daughter Brooke, posted a picture of Tommy with a grumpy expression, which was accompanied with the caption: "Tommy not so pleased that he is having a baby sister!!! Lol (sic)".
The former prison officer found out she was pregnant last month after taking a test in an ASDA supermarket while her husband Craig, 40, was off doing the food shopping.
She said previously: "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."
Meanwhile, the songbird has been forced to delay her tour, which was planned for October, and was initially worried her management would be disappointed by the news.
She said: "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."
