Geri Halliwell expecting second child: '#mamaspice'

LONDON, Oct. 10 (UPI) -- Geri Halliwell is going to be a "#mamaspice" for the second time.

The 44-year-old Spice Girls singer, aka Ginger Spice, announced she's pregnant and expecting with husband Christian Horner in an Instagram post Monday.

"God bless Mother Nature #mamaspice," she captioned a line drawing of a pregnant woman.

Halliwell and Horner married in Bedfordshire, England, in May 2015 after more than a year of dating. The singer is already mom to 10-year-old daughter Bluebell with ex-partner Sacha Gervasi.

"Having Bluebell changed everything," she told the Telegraph in July. "You have someone else to think of; you want to pass on all the right lessons and be a good mother. It's so lovely to share that with my husband be our own team."

"I can be totally nerdy in front of him. He's as geeky and silly as me," she added of Horner. "I never thought I'd get married because I never thought I'd meet someone I could be myself with, and who I wanted to be with forever."

Halliwell and fellow Spice Girls Mel B and Emma Bunton were planning to celebrate the 20th anniversary of the group's album Spice, albeit without Victoria Beckham and Mel C. It is unknown if the singer's pregnancy will affect the reunion.

"We're gonna perform and celebrate together for the people," Mel B revealed on The Late Late Show with James Corden in September. "I think 'cause we're a British band we're probably gonna start in London and then work our way around."
