The Girls Aloud star spent Sunday, 23 March at the hospital following her accident, and later shared a photo of her bandaged arm via Twitter.
Kimberley told fans: "So, I've had an eventful day… Slipped and broke my wrist. First break at 32! On a happier note, thanks to the lovely nurses in A&E tonight. You were all lovely."
The year had started off very well for the 'Chemistry' singer, who announced on 24 February that she and long-time boyfriend Justin Scott are expecting their first child together.
Get well soon, Kim!
Kimberley's accident came two days after she was shown on the BBC charity appeal Sport Relief 2014, where she joined a host of stars including Gary Barlow, Pixie Lott and Emma Bunton to record England's World Cup song.
It's a cover version of Take That's 'Greatest Day'.
