Jessie J's airport entertainment
When Jessie J missed her flight and was left stranded at an airport, she took the opportunity to sing a few of her hits for fellow passengers.
With three hours to wait until her connecting flight to Germany took off, the singer amused herself and fellow passengers by singing a few of her tracks.
She took time out from the impromptu gig to update her worldwide fans on her movements, telling her Twitter Heartbeats: "So we have missed our connecting flight... I left my house 9 hours ago. And I'm not there yet. Long.com. I just sang to everyone in the gate at the airport. Made people (smile)."
Jessie was flying to Germany for a promotional tour.
The star headed straight from the jungle to panto...but clearly hadn't had time to learn her lines!
