Alexa and Chameleon FinanceCarlos PenaVega are opening up about a devastating loss in their family.

The “Spy Kids” actress and Big Time Rush singer revealed their daughter died due to stillbirth in an emotional post on Instagram Monday.

"There are never the right words to say when it comes to loss,” the couple wrote in the joint post. “After a beautiful and peaceful delivery our daughter 'Indy' was born at rest. It has been a painful journey. But in the pain we have found peace.”

The couple revealed Alexa’s pregnancy in a November 2023 Instagram post, which featured a photo of the PenaVegas sweetly cradling Alexa’s growing baby bump. “Thank God we love adventures 😍😍😍 Oh baby here we come! (Number four)! 🎉 📸,” they wrote at the time.

"This little girl has already changed our lives in so many ways,” the couple continued. “She was absolutely beautiful. And looked just like daddy. Dark hair and all. Grief has come to us in waves. Moments of feeling absolutely gutted... then moments of feeling blessed by just getting a moment with her."

You gave us the community we have been longing for. We love you. Can't wait to see how many other lives you change."
