Aaron Paul and his wife, Lauren, have welcomed a baby girl. The Kind Campaign founder announced the happy news via Instagram and perfectly summed up what it feels like to become a first-time mom.

“There are no words that will ever be able to explain what just happened to my heart,” Lauren captioned a photo of her newborn daughter wrapped in a hospital blanket. 

The Breaking Bad actor also took to Instagram to share the news. “My heart,” Aaron wrote alongside a black-and-white portrait of his daughter’s teeny tiny foot.

The couple tied the knot four years ago and announced they were expecting back in September.
