Katy Perry has lost her pre-Christmas cheer after her luggage went missing during a long-haul flight.
The I Kissed A Girl took to her Twitter.com page to tweet about the mid-air mishap - and she's not happy.
She wrote, "Been flying for bout 26 hours now...& NOW u tell me u lost my luggage (sic)? Hello tipping point! Remind me to not travel the week before xmas."
