Cameron Diaz Says Husband Benji Madden 'Needs to Do a Kids' Album' After Making Up Songs for Daughter Raddix

Cameron Diaz has a new business venture for her husband.

While appearing on Wednesday's episode of The Tonight Show Starring Jimmy Fallon, the actress, 51, revealed that she has a new idea for her husband, Good Charlotte guitarist Benji Madden, 44. Talking with Jimmy Fallon about her husband's recent concerts, Diaz says that Madden's singing doesn't stop when he leaves the stage.

"He's like, Benj at home, being the best dad ever and running all of his businesses, and then he just gets up there and he's like, 'Yeah, all right, pyro! Pfft!'" Diaz says, referring to Madden's show at the When We Were Young Festival.

"When he's at home, does he do songs for your daughter or...?" Fallon asks.

"Yeah, he makes up — he has, honestly, I'm like, 'Why don't we just...you need to do a kids' album,' because he has the best songs," the star says. "They play in my head all the time because he sings them to her and she knows the words. And it's the sweetest thing ever. It really is. It's so...it kills me."

"He has some bangers," Diaz jokes. "I'm telling you."

Diaz and Madden share daughter Raddix, 3½.

While the couple is notoriously private about their daughter, they have occasionally opened up about their life as parents.

Diaz and Madden announced the birth of their daughter with an emotional post on the actress' Instagram that read, "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."

She went on to say that while they were "overjoyed to share this news," they "also feel a strong instinct to protect our little one's privacy." Diaz added, "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."

During a July 2020 interview on The Tonight Show with Jimmy Fallon, Diaz stated that Raddix already loves music. The Bad Teacher star said they have "Baby Shark, "Elmo's Song" and Sesame Street "on rotation," adding, "It's crazy. We're like jamming out over there, and she loves it!"

Diaz added that her daughter's music taste "changes," saying, "When we go on car drives, Benj will put on some Cuban, Afro-Cuban music, and she is in her car seat and her little legs are kicking ... and I'm like, 'Yep, that's my girl!' "
