Kasabian's Tom Meighan - E.T. bike: Possibly the greatest purchase on this list, Meighan reportedly spent months haggling with a collector to buy the E.T. bike - the one ridden over the moon by little Elliot and his alien buddy in the most iconic scene from the Spielberg film.
Justin Hawkins - His own album from eBay: When promo copies of The Darkness' One Way Ticket To Hell And Back were sent to music industry professionals in 2005, one of them ended up on eBay. To stop it from being heard before its release, Justin Hawkins spent 350 quid buying it back. This, presumably, was before the ubiquity of online music leaks.
Jay Z - Dragon egg from Game of Thrones: Admittedly, this is according to the very unsure testimony of GoT actress Emilia Clarke, whose exact words were, "Apparently Jay Z bought one for Beyonce or something, I don't know." But if you were Jay Z, why on earth would you NOT buy a dragon egg?
Taylor Swift - Porn URL: Not quite as strange as it first sounds, this one. Swift bought the URL taylorswift.porn in a bid to stop others from setting up pornographic websites in her name. She also bought taylorswift.adult for good measure.
Katy Perry - a convent: This particular transaction is yet to be finalised, and if a pair of unhappy nuns - who object to her 'I Kissed A Girl' past - have their way, it never will be. According to the nuns at the California convent, Perry intends to live there with her mother and grandmother as a way of "finding herself."
Adele - Luxury caravan: The singer treated her grandma Doreen to a 23,000 pound luxury caravan for her 70th birthday, so she could spend weekends at her local caravan park in Essex with her dog. Rock 'n roll.
The Verve's Richard Ashcroft - a live turkey for Christmas: After his son turned vegetarian, Ashcroft decided to buy a live turkey from a local butcher. Rather than slaughtering it for Christmas dinner, he kept it as a family pet, and named it Lucky.
Dr. Luke - A $10,000 toilet: This was a gift of sorts for Miley Cyrus - the producer bet Cyrus that 'Wrecking Ball' wouldn't reach No.1 (he of little faith), and agreed to buy her a Numi toilet if he was wrong. He was. "I'll think of him every time I go," said Cyrus.
Muse's Matt Bellamy - Jet pack: OK, technically it's a powered para-glider, but jet pack sounds much more extravagant. Bellamy spent 10,000 pounds on the jet pack after seeing an opponent flying into a boxing match with Mike Tyson using one. Though he insisted he'd nearly obtained his license, he later admitted he's only actually used it once.
