Congrats to former Spice Girl Melanie Brown and her husband Stephen Belafonte who welcomed their first child together into the world Thursday night (Sept. 1). The singer took to her Twitter page in the wee hours of Friday morning after giving birth to her new baby girl to share the joyful moment with her fans. "Finally our baby arrives," she wrote. "Stephen nearly passed out, Phoenix screamed, I laughed so hard the baby popped out!!! She is just sooo amazing!!"

Brown's rep also confirmed the happy news, stating to PEOPLE magazine: "This evening Melanie Brown and husband Stephen Belafonte welcomed their new baby girl in Los Angeles. This is the first child for Mel and Stephen and both mum and baby are happy, healthy and doing well."

Brown, 36, is already a mom to daughters Phoenix (12) and Angel (4), and her film producer hubby, 35, already has one daughter, six-year-old Giselle.

Following her first tweet about the new bundle of joy's arrival, Brown tweeted again at her loving husband, saying, "I didn't think it was possible but I love you even MORE now honey, we have a truly amazing family xxxx."

Brown's fellow Spice Girls members, Victoria Beckham and Emma Bunton, have also welcomed their own children into the world recently. Beckham gave birth to her fourth child and first daughter, Harper, just seven weeks ago, while Bunton welcomed son Tate back in May.
