The X Factor winner, 36, attended Saturday night's British Soap Awards (24 May) at London's Hackney Empire in a stunning black maternity frock, with nude lace detail.
And while we think the floor-length Rosa gown - from a range of maternity wear by Tiffany Rose - flattered her blossoming belly perfectly, Sam took to Twitter to say what she really thought!
Alongside a picture of herself at the prestigious TV event, the 'Skyscraper' singer wrote: "God I look HUGE! Lol."
Well, you are six month's pregnant with your third child, Sam!
The down-to-earth star also posted a selfie before having any make-up applied to prove that she's just like the rest of us and needs a little bit of help before a big glitzy event.
She also showed that she can still get a little bit starstruck... Posing for a picture backstage with EastEnders actor Shane Richie, Sam wrote the message: "So good to see ya Shane xxx."
Earlier the same day, Sam shared a picture of her latest baby scan after a mystery hospital visit left some of her fans worried about her.
Alongside a grainy black and white photo of her unborn baby, Sam wrote: "To all my concerned fans x me and baby are fine. I'm out of hospital and all is well x."
Sam, however, did not elaborate as to why she had been in hospital in the first place. But, if her appearance at the British Soap Awards is anything to go by, she looks the picture of health.
She announced she was pregnant with her third child in March, and later confirmed she was expecting a daughter. She has been married to daddy Craig for 11 years.
