The 53-year-old rocker-turned-photographer and his partner Alicia Grimaldi - with whom he has 18-month-old daughter Mirabella Bunny Grimaldi-Adams - will welcome another child into the world next year.

He tweeted: "Alicia's either eaten too much chocolate cake or we're expecting another baby ... I think it's a baby."

His representative added to People.com: "There's another baby on the way for singer Bryan Adams and Alicia Grimaldi.

"Their daughter, Bunny Grimaldi-Adams, is now 18 months old, and the new baby is due next year."

Brian joked about the arrival of his "Easter bunny" last year.

Announcing the birth of his daughter, he said: "I'm really proud to announce on 22 April, Mirabella Bunny was born. Mother and baby are both well and happy. Thanks in advance for your kind thoughts and wishes.

"She arrived like all good Easter bunnies on Easter Friday."

Friends of Alicia - who is believed to be living with the singer-and-photographer in London - were said to be shocked when Bryan announced the pregnancy last March as many people had no idea they were even dating.

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."

Alicia is a charity activist and one of the trustees of the Bryan Adams Foundation, a charity registered in the UK.
