The X Factor 2013 winner, 36, can be seen smiling happily for cameras as her proud husband Craig lays his hand protectively on her blossoming baby bump.
Sam and her hubby arrived in advance of her performance at Manchester Pride's Supersonic event - an exclusive red-carpet charity event which took place at Manchester Airport's Concorde Hangar last night (11 April).
The 'Skyscraper' singer arrived wearing minimal make-up, with her hair tied back, and her pregnant tum covered in a leopard-print top. Craig looked casual in a blue T-shirt and jeans.
Later, the couple glammed up for the glitzy evening event.
Sam wore all black in a long-sleeve lace-effect top, leather trousers and heels, while Craig stayed in jeans but teamed them with a smart light blue shirt.
Sam entertained guests throughout the evening until a DJ took over, when we're sure she headed home to put her feet up!
X Factor's 10th winner Sam announced in March that she's pregnant with her third child.
