Geri Horner has shared a new picture of her bump.

The 44-year-old singer - who already has 10-year-old daughter Bluebell from a past relationship - and her husband Christian Horner, 42, are expecting their first child together and Geri posted a picture of herself in a form-fitting dress, which shows off her bump.

Geri's new picture has been taken in a recording studio and she simply captioned it, ''in the studio''.

She recently reunited with Spice Girls bandmates Mel B and Emma Bunton to work on new material.

Geri's spokesperson recently confirmed the pregnancy news, saying: ''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 borrowed a line from her single 'It's Raining Men' to announce her happy news on Instagram.

She wrote: ''God bless Mother Nature #mamaspice (sic)''

Geri previously described Formula One boss Christian - who she married last year - as her ''best friend''.

She said: ''My husband is my best friend. He knows me inside out, I don't edit myself with him. It was a big learning curve.''

And late last year, the 'Lift Me Up' hitmaker admitted she and Christian - who has a three-year-old daughter, Olivia, from a past relationship - would love to have another child and would even consider adoption.

She said: ''If it happens it happens and that will be amazing. But we are already blessed with two girls.

''We might think about adoption but to be honest, we know we are so lucky and so happy with things as they are, you have to know when not to push your luck.''
