The images show an adult hand alongside the newborn's hand, Lavigne holding the baby, and three pairs of checkered Vans shoes, adult and baby sizes, on a skateboard. Descriptions of the photos differ. Some describe them as black-and-white, and the baby's outfit is variously called cheetah print or leopard print. The caption borrows from the lyrics of her 2007 single "Girlfriend."

Lavigne has not given the baby's name or birth date. She has not named her partner, and the person whose hand appears in the photos is unidentified. She did not say whether he is the child's father. It was her first personal update on the platform in more than a year. She had not announced a pregnancy, and she turned off comments on the post. It drew more than a million likes within two hours.

A representative for Lavigne told People that she is spending time with her family and working on a new album, and thanked her fans for their support.

Lavigne has long kept her personal life private. Her last publicly known relationship was with the rapper Tyga, which reportedly ended in 2023. She was also engaged to the musician Mod Sun, an engagement that ended in February 2023. She was earlier married to Deryck Whibley of Sum 41 and then to Chad Kroeger of Nickelback.

She has talked about motherhood in interviews for years. In 2013 she said she wanted "one or two" children, and she has also said she was not ready for children in her twenties. In a 2024 podcast interview she stressed the importance of compatibility and trust in a partner.

Lavigne became famous at 17 with her 2002 debut album "Let Go," which includes "Complicated" and "Sk8er Boi" and has sold more than 17 million copies worldwide. Her next two albums, "Under My Skin" in 2004 and "The Best Damn Thing" in 2007, both debuted at No. 1 on the Billboard 200. "Girlfriend," from the latter, was her first U.S. No. 1 single.
