The post featured a mix of current and throwback images, showing Axl’s journey from infancy to adolescence. One recent photo captured the birthday boy striking a serious pose, his blonde hair styled into tousled spikes, as he stood nearly as tall as his famous mother.
“It’s so beautiful to watch you grow into the kind, silly, and cool dude you are. You are so tough bruh,” Fergie continued in her tribute. “Happy 13th Axl Jack. I love you.”
