Avril Lavigne Is a Mom! Singer Welcomes Her First Baby With Mystery Partner

Avril Lavigne got her happy ending. The 42-year-old singer revealed Friday (Nov. 13) that she and her partner — a mystery man whose identity has not been revealed — have welcomed a child together, shocking fans who’d had no idea she was expecting.

The Billboard Hot 100-topping first-time mom broke the news with a set of photos on Instagram, all black-and-white. The first shows her baby girl’s tiny hand holding onto Dad and Lavigne’s hands, while the second features the pop-rocker cradling the newborn in her arms. A third snap fittingly shows three pairs of shoes — checkered Vans, Lavigne’s signature footwear — lined up in a row, one of them considerably smaller than the others.

“Our Mini F–king Princess has arrived,” she wrote in the caption, referencing a lyric from her 2007 Hot 100 No. 1 single, “Girlfriend.” (“Don’t pretend, I think you know I’m damn precious/ And hell yeah, I’m the motherf–kin’ princess.”)

Before the announcement, Lavigne hadn’t posted on her Instagram in more than a year — and now, fans know what she’s been up to. Though the musician turned off comments on her baby news, fans flocked to the replies of her second-most recent post — a roundup of October 2025 snaps from When We Were Young Festival — to share in their surprise.

“I’M SORRY WHAT–,” one person wrote, while another commented, “WHAT THE HELL AVRIL!!!! OMG.”

Clearly, Lavigne is good at keeping her personal life private. In addition to keeping her motherhood journey private, fans still have no idea who the man in her life is. The Grammy nominee hasn’t been in a public relationship since her 2023 romance with Tyga, before which she was engaged to Mod Sun.
