The Spice Girls favourite was smiling ear to ear as she attended the Attitude Magazine Awards in London on Monday night (10 October) shortly after confirming she's expecting a child with husband Christian Horner.
Geri, looking beautiful in blue, was joined by Formula One team boss Christian at the event, where she picked up the 'Honorary Gay Award'.
Her former Spice Girls bandmate Emma Bunton was also in attendance, and the women were snapped laughing and hugging on the red carpet.
Emma also placed a hand on Geri's bump while posing for pictures.
She later tweeted: "Congratulations to my gorgeous friend @therealgerihalliwell! Another #SpiceBaby on the way."
Geri, 44, and Christian, 42, announced their happy news via an Instagram post on Geri's account earlier in the day, posting a cartoon of a pregnant woman with the caption: "God bless mother nature #mamaspice."
The couple's rep confirmed: "Geri and Christian are absolutely delighted to announce they are expecting their first child together. The couple are overjoyed with the good news and cannot wait to welcome the newest addition to their family."
Geri and Christian married in May 2015 in a star-studded Bedfordshire ceremony attended by guests including Emma, Jennifer Saunders, Myleene Klass, Amanda Holden and illustrious names from the racing world.
Popstar Geri is already mum to daughter Bluebell, ten, while Christian has a daughter, Olivia, who is two.
The little one will be the 12th Spice baby: Victoria is mum to sons Brooklyn, Cruz and Romeo, and daughter Harper. Emma has sons Tate and Beau. Mel B has daughters Phoenix, Angel and Madison, and Mel C has daughter Scarlet.
