The 51-year-old rocker and his personal assistant, Alicia Grimaldi, are expecting a baby in May.
Bryan told TV show Entertainment Tonight Canada: “Alicia Grimaldi and I are expecting a baby. She helped me start my foundation years ago and it looks like she’ll be running the family now!”
Insiders claim the baby news is likely to come as a shock to friends of Alicia, who is believed to be living with the singer-and-photographer in London.
One insider said: "Many of their friends still don't even know that they are a couple, but they are living together at his house."
A spokesperson for Bryan declined to comment on the nature of their relationship, but Bryan added: “Thanks for your support and kind messages, we appreciate it greatly.”
Alicia is a charity activist and one of the trustees of the Bryan Adams Foundation, a charity registered in the UK.
According to the foundation’s website, she graduated from the prestigious Cambridge University in 2001 with a degree in social and political sciences.
