They can now officially change their name to the Spice Moms. Melanie "Sporty Spice" Chisholm was the only one of the Spice Girls who wasn't a mom yet, but that's all going to change. The singer, who's expecting with her boyfriend, Thomas Starr, posted her exciting baby news on her official web site. "Well, I can now announce that Tom and I are expecting a baby and we are very happy. As I'm sure you'll understand we needed time to wait for results and tell our families. Thank you for all your kindness, good wishes and support (even if it was based on speculation!)," wrote Mel. "I will be taking it easy but am also excited to start writing for the fifth album. I'll need some time off to be a mum but, before you know it, I'll be back." Congrats!
