Melanie Chisholm is ready to spice up her life – with a baby!
The sometime Sporty Spice, 34, and her boyfriend of six years, property developer Thomas Starr, confirmed the pregnancy on her Web site
"Some happy news," she wrote. "I can now announce that Tom and I are expecting a baby and we are very happy."
Mel C. follows in the footsteps of her former Spice Girls bandmates – Victoria Beckham
, Melanie Brown, Geri Halliwell and Emma Bunton – who have all become moms.
Baby buzz building began last week, when Chisholm wore a baggy dress during a show in Liverpool last week.
"As I'm sure you'll understand, we needed time to wait for results and tell our families," she explained on the site.
Even as she prepares for motherhood, the singer says she's "also excited" to begin writing songs for a new solo album.
"I will need to take some time off to be a mum," she wrote. "But, before you know it, we'll be back."
Her "very excited" trainer, Matt Roberts, adds: "Her pregnancy is great news. Melanie is fit, healthy and well and I am sure she will sail through her pregnancy, and I know that she will look great afterwards too, as I will be making sure that she does!"
