Punk star Avril Lavigne has announced the birth of her first child, a baby girl, sharing the news with fans on Instagram. The singer posted black-and-white images confirming the newest member of her family, including a photo of herself and another individual holding the baby's hand, a picture of her carrying her newborn, and three pairs of sneakers, one of them an infant's pair, arranged on a skateboard.

In the caption, Lavigne wrote, "Our Mini F***ing Princess has arrived," alongside emojis of a ribbon, crown, baby bottle and pink heart, and she used an expletive for emphasis. Comments on the post were turned off. Lavigne has not revealed who the father of her baby is. A representative told People magazine that Lavigne "has been enjoying time with her family while working on her new album and wants to thank the fans for all of their love."S1S2
