Alesha Dixon, 40, announced she was expecting her second child, with her partner Azuka Ononye, on the show at the beginning of the week.
And on tonight’s final semi-final of Britain’s Got Talent, Alesha looked glowing in a stunning, dazzling number.
As she walked onto the stage with her co-stars, Alesha beamed away as she showed off her blossoming baby bump.
Her rotund stomach couldn’t be miss in the figure-hugging dress, which featured a slit to show off her pins.
The glistening garment featured an halterneck design and fell into an asymmetrical split, showing off her slender pins.
The singer’s brunette locks were styled in tousled waves and she kept the accessorises to a minimum.
Alesha couldn’t have looked happier as she sauntered on to the stage in front of the roaring audience.
She stood with Amanda Holden on her right, whilst holding David Walliams’ hand to her left.
Amanda, 48, put on a very leggy display on the night in a skimpy metallic frock which featured exaggerated shoulder pads.
The short dress enabled the actress to show off her incredibly toned pins, elongated in a pair of perspex heels.
Alesha also uploaded a picture of herself posing in her jaw-dropping frock on Instagram.
She captioned her post: “Live Show 5! @bgt @rahulb91 Dress @yousef_aljasmi Shoes @gianvitorossi Jewellery @monicavinader.”
Alesha was inundated with messages with Pussycat Dolls singer, Kimberly Wyatt, congratulating the star, saying: “Congratulations gorgeous!!! I am so Happy for you and your bump! Have a great show! Xx.”
Girls Aloud star, Kimberley Walsh, added: “Congratulations babe so happy for you both.”
Former X Factor winner Louisa Johnson commented: “Omg,” with a fire emoji.
Meanwhile, Alesha spoke about her baby’s gender earlier this week on Britain’s Got More Talent.
The star was quizzed by host Stephen Mulhern on the ITV2 show bu refused to give much away.
The presenter asked: “Can you give us an exclusive? Is it a boy, or is it a girl?”
The singer giggled as she tried to avoid the question by explaining: “I don’t know yet.”
The Britain’s Got Talent judge finally gave in and revealed she has in fact found out whether she was expecting a boy or a girl, as she admitted: “I’m lying.”
