Avril Lavigne became a shop assistant on Tuesday (03Apr12) to support a Canadian supermarket's new charity drive.
Bosses at Safeway have launched a fundraising campaign for the Special Olympics and Easter Seals, an organisation which aims to enhance the quality of life of disabled Canadians.
Lavigne supported the scheme at her local Safeway store and helped pack bags to raise awareness of the initiative.
In a post on her Twitter.com page, she writes, "Just bagged groceries with Safeway to support their people with disabilities campaign with Easter Seals! I got a medal today!"
The Sk8er Boi hitmaker has also filmed exclusive videos for fans in exchange for a $5 donation to the fundraiser.
