The 42-year-old artist shared the joyous news on her Instagram, posting a series of intimate black-and-white photographs to announce the arrival.
In the shared images, Lavigne and her partner are seen holding their newborn’s hand, alongside a sweet photo of the singer holding the infant close to her chest.
A final image features three pairs of checkered Vans sneakers arranged on a skateboard, two adult sizes resting beside a tiny pair of baby Vans.
Lavigne has not yet publicly identified the baby’s father or confirmed her current relationship status.
Announcing the birth to her followers, Lavigne wrote, “Our Mini F—ing Princess has arrived.” A representative for Lavigne told that the singer has been taking time to bond with her newly minted family of three.
