LOS ANGELES: Canadian rocker Bryan Adams has become a father for the first time at the age of 51, People magazine reported on Thursday.

The “Summer of '69” musician's personal assistant gave birth to a daughter, Mirabella Bunny, on April 22, People said on its Web site. Adams' spokeswoman did not respond to messages seeking confirmation.

The mother, Alicia Grimaldi, is a long-time employee who helps run Adams' charitable efforts. She and the baby were both “well and happy,” Adams was quoted as saying in the report.

Adams maintains strict secrecy about his private life, and the nature of his personal relationship with Grimaldi has not been disclosed.

Britain's Sunday Telegraph, which broke the news of his pending fatherhood in March, quoted an unidentified source at the time as saying that many of Adams' friends did not know he was in a relationship.

Grimaldi, a Briton, helped set up the Bryan Adams Foundation in 2004, three years after graduating from Cambridge University, according to Adams' Web site.

Adams, famed for such rock songs as “Summer of '69,” “Cuts Like a Knife,” and “Everything I Do (I Do It For You),” will launch a European tour next month.
