Congratulations to Benji Madden of Good Charlotte and actress Cameron Diaz on their bundle of joy!  Today the couple announced the birth of their baby girl, Raddix Madden, on Instagram.

The caption reads “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…”

Madden and Diaz got engaged in December of 2014, then wed in January of 2015.  This is their first child together. Sounds like they’re keeping things pretty private, but are excited to start the new year together as a family!
