Musician Bryan Adams will be a first-time father at age 51. The Canadian rock star's personal assistant, Alicia Grimaldi, is pregnant with the couple's child, which is due in May.

“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!” Adams told ET Canada.

Adams is notoriously private about his personal life, and many of his friends didn't even know he and Grimaldi were an item.

Adams, who has never been married, previously dated supermodel Elle MacPherson and actress Pamela Anderson. It is rumored he also had an affair with the late Princess Diana.
