Baby spice! Geri Halliwell is pregnant with her second child. The Spice Girls singer, a.k.a. Ginger Spice, announced the news with a cute Instagram photo on Monday, October 10.

"God bless Mother Nature #mamaspice," Halliwell, 44, captioned a sketch of a woman with a growing baby bump.

The British star married her boyfriend, Christian Horner, in May 2015 after nearly a year of dating. (They previously were friends for five years.) They exchanged vows at St. Mary's Church at Woburn Abbey in Bedfordshire, East England.

"I can be totally nerdy in front of him," Halliwell gushed of her beau to The Telegraph back in July. "He's as geeky and silly as me."

Halliwell is already mom of daughter Bluebell Madonna, 10, with her ex, screenwriter Sacha Gervasi. "Having Bluebell changed everything. You have someone else to think of; you want to pass on all the right lessons and be a good mother," she told the publication at the time. "It's so lovely to share that with my husband and be our own team."

Halliwell might be on the road during her pregnancy. Back in March, Us Weekly exclusively revealed that she and her former bandmates — Melanie "Scary Spice" Brown, Melanie "Sporty Spice" Chisholm and Emma "Baby Spice" Bunton — are planning a reunion tour. (Victoria "Posh Spice" Beckham is sitting this one out.)

"This has been in the works for the past year," an insider told Us. "The girls have long been keen to do a major reunion tour together."
