Avril Lavigne is a mom. The 42-year-old singer announced on Friday that she secretly welcomed her first child, a baby girl, sharing the first photos of her newborn on Instagram.

"Our Mini F—ing Princess has arrived 🎀👑🍼🩷," Lavigne wrote alongside the carousel of photos. She did not reveal the baby's name, and she has not said who the baby's father is.

In the first photo, Lavigne and her mystery partner held their baby daughter's tiny hand. The next image showed the "Complicated" singer cradling her newborn, who was dressed in a cheetah-print outfit. Lavigne also shared a picture of three pairs of black-and-white checkered Vans sneakers — seemingly belonging to her, her partner and their daughter — a nod to the "Sk8er Boi" aesthetic that made her famous.

Lavigne had kept the pregnancy entirely private. She was last seen publicly in April, leaving the Chateau Marmont hotel in Los Angeles after a night out with friends. In July, she was reportedly a surprise performer at an after-party for Taylor Swift and Travis Kelce's New York City wedding.

Her last publicly known partner is rapper Tyga, whom she started dating in early 2023. The pair split in June 2023, briefly reunited, and People confirmed that October that the romance was "totally done." Before Tyga, Lavigne was engaged to fellow singer Mod Sun; they called it quits in February 2023. She was previously married to Sum 41 singer Deryck Whibley from 2006 to 2010 and to Nickelback singer Chad Kroeger from 2013 to 2015.
