The singer was spotted earlier today having a grand old time aboard a yacht off the coast of Saint Tropez with some of her girlfriends and she looked like she was really enjoying herself.
The group of girls were photographed having a dance party on the boat before taking the f�te into the water. (Check out the photo of Lavigne's leap into the sea, below.) The 26-year-old Canadian swung her shirt around her head as she and her pals laughed and danced the day away.
This girls only trip left Lavigne's main man, Kardashian step-brother Brody Jenner, alone to fend for himself. The pair have been together for over a year and even inked themselves with matching tattoos.
