Move over, Emma Bunton: There's a new Baby Spice in town!

On Saturday (January 21), former Spice Girls singer Geri Horner, a.k.a. Ginger Spice, announced the birth of her second child—her first with husband Christian Horner—a baby boy named Montague George Hector Horner.

"Christian and I are delighted to announce our baby boy was born this morning weighing 7lbs 8oz," the pop artist, who also has a 10-year-old daughter named Bluebell, from a previous relationship, shared on Twitter. (She is also the stepmother to Olivia, Christian's daughter from a previous relationship.)

On Instagram, the "Mama" singer shared a sweet black-and-white photo of her new baby's tiny feet, writing, "Montague George Hector Horner arrived this morning, a beautiful little brother for Bluebell and Olivia."

But Ginger wasn't the only Spice who celebrated baby Montague's arrival: On Twitter, Bunton (Baby Spice) and Melanie C (Sporty Spice) shared their congratulations with Horner.
