The "Summer of '69" hitmaker and his longtime girlfriend and personal assistant, Alicia Grimaldi, welcomed their baby girl Mirabella Bunny in April 2011 and now the Adams family is set for a new addition within months.

A representative for the singer tells 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."

And Adams, who celebrated his 53rd birthday on Monday, jokes, "Alicia's either eaten too much chocolate cake or we're expecting another baby. ... I think it's a baby."
