The singer's sister Emily recently married the man who "bought" her, he reveals

Celebrities have auctioned off some pretty strange things (Corey Haim’s baby teeth, anyone?), but James Blunt tops them all: He sold his sister.

The “You’re Beautiful” crooner recalls in British GQ: “I came back to the flat where my sister was staying and she was crying because she couldn’t get to a funeral in Ireland. The planes were on strike, the ferry was out of season, and there were no trains.”

So he came up with an innovative solution to the problem. “I ended up whacking it on eBay: ‘Damsel in distress seeks knight in shining armor! Desperate to get to a funeral in southern Ireland, please help!’ The bids flooded in and the guy who won had a helicopter.”

And now, the fairy tale has a happily ever after ending: “He flew her to the funeral,” Blunt says. “That was three years ago. This summer they’re getting married. That was the stupidest thing I’ve ever sold on eBay – my sister.”
