LOS ANGELES, Nov 14 — Avril Lavigne is officially a mum after announcing the arrival of her first child, a baby girl, in a surprise social media reveal.

The Canadian singer shared the happy news on Instagram, posting a series of black-and-white photographs featuring the newborn.

“Our Mini F****** Princess has arrived,” Lavigne wrote in the caption.

The images showed the Complicated hitmaker holding her daughter’s tiny hand and cuddling the infant, while another featured three pairs of chequered Vans shoes on a skateboard, including a miniature pair for the newest family member.
