What's better than one birthday? Two! Today, Good Charlotte's Joel and Benji Madden are celebrating their joint 37th birthdays!

These two have certainly achieved a lot in their musical careers, founding the rock band Good Charlotte back in 1996, followed by The Madden Brothers in 2014. Currently, Joel is a judge on The Voice Australia and Benji has also appeared on the show as a guest judge.

While the duo is certainly musically inclined, they're family men first and foremost. Joel has been with his wife, Nicole Richie, since 2006 and they tied the knot in 2010, serving up #RelationshipGoals ever since. The couple are also doting parents daughter Harlow Winter Kate and son Sparrow James Midnight.

As for Benji, his sister-in-law Nicole actually introduced him to his wife, Cameron Diaz, whom he wed in 2015. Months later, Benji commemorated his love for Diaz by tattooing "Cameron" across the chest. #Swoon.

In honor of the identical twins' birthday, we're taking a look at 9 of their sweetest family photos, which prove that the Madden brothers are all about that family love:
