Kanter is also mother to Condou's first child, two-year-old Georgia Mae.
Fellow street actor Kym Marsh divulged Charlie's news via her column in New! magazine.
"My friend Charlie Condou... came to visit last week and told me some exciting news... He and his best friend Catherine are having another baby together," she wrote.
"They already have a daughter, Georgia Mae, two, who splits her time between living with her mum and living with Charlie and his partner Cameron. I'm delighted for him!"
The news was confirmed by Charlie himself today, who revealed the baby is a boy due in January.
He also playfully took to Twitter to announce, "I'm having another baby! Can't wait, though it took me ages to get my figure back last time."
