The singer, 32, reunited with best friends Cheryl Cole and Nicola Roberts in London last night (26 April) and no doubt Kim's impending birth was a hot topic of conversation!
In a photo posted by Cheryl Cole on her official Instagram, the three former bandmates can be seen striking a pose at The Box in Soho.
And Nicola, 28, can be seen putting a protective hand on Kim's growing belly.
Alongside the touching snap, Cheryl wrote the simple message: "3 women and a baby."
Celebrating the birthday of mutual friend and former Girls Aloud choreographer Beth Donnan, the girls were clearly having a fun night together over a few drinkies. Non-alcoholic for Kim naturally!
Nicola shared a picture of the four girls with their arms around each other with a lovely message to them, saying: "Sex in the city. Friends forever. No place I'd rather be."
At 3am in the morning (good going girl!), Kim took to Twitter to thank her old friends for a good night out.
She said: "My girls were looking after me tonight."
'The Promise' singer Kimberley announced her pregnancy in March. It will be her first child with long-term boyfriend Justin Scott.
She will be the second Girls Aloud member to have a baby, after Nadine Coyle gave birth in February.
