The statement read: ''Happy New Year from the Maddens! We are so happy, blessed and grateful to begin this new decade by announcing the birth of our daughter, Raddix Madden. She has instantly captured our hearts and completed our family ... While we are overjoyed to share this news, we also feel a strong instinct to protect our little one's privacy. So we won't be posting pictures or sharing any more details, other than the fact that she is really really cute!! Some would even say RAD:) From our family to all of yours, we're sending our love and best wishes for a Happy New Year and Happy New Decade ... Sincerely, Cameron&Benji (sic)''

The baby news comes just a few months after Cameron gushed over married life with the rocker.

Speaking in August, the actress said: ''Getting married to him was the best thing that ever happened to me. My husband's the best. He's the greatest human being, and he's my great partner. Marriage is certainly hard, and it's a lot of work. You need somebody who's willing to do the work with you, because there's no 60-40 in marriage. It's 50-50, period. All the time.''
