Geri Halliwell Horner is about to be a mama for the second time!

The former Spice Girls member — known as Ginger Spice throughout her time with the group — is pregnant and expecting her first child with husband Christian Horner, her rep confirms to PEOPLE.

Geri took to Instagram Monday to confirm the exciting news.

“God bless Mother Nature #mamaspice,” Geri, 44, wrote next to a drawing of a pregnant woman underneath the same text.

Geri and the Formula1 racing team boss have been together since early 2014, and were married in England in May 2015. Among the guests were Geri’s former bandmate Emma Bunton, A.K.A. Baby Spice.

The fashion-forward bride wore a gown by London-based coture designer Phillipa Lepley and arrived at the event in a vintage Rolls Royce, while her beloved arrived in a 1965 Aston Martin.

The newest member of the Horner family will join 10-year-old big sister Bluebell Madonna, Geri’s daughter from a previous relationship.
