After his much-talked about trim last week, Justin presented Ellen with a few precious strands of his hair, telling her, "I'm giving pieces of it to different people. We're doing something special. We want you to donate it to whatever charity you want."
Ellen put the hair up for auction on ebay, with all proceeds going to the California animal rescue organisation The Gentle Barn.
Bidding started at $10 and after just two days it's already hit $7000... and there's still five days to go.
As for whether any of the people bidding on the hair actually have enough money in their piggy banks to pay for it, we'll see about that.
