Tragedy struck after a Britney Spears show last night.
After attending Spears' Femme Fatale concert, a 31-year-old woman was killed when she fell from a fairground ride set up outside Dublin's O2 arena.
"I was saddened to hear of the tragic accident in Dublin. My heart goes out to the family. -Britney," the singer tweeted today.
"We can't say [what happened], it all happened so quick," Kenneth McFadden, owner of fair operator McFadden Entertainment, told Dublin's Independent newspaper. "We are just in bits at the moment, we are just devastated."
The woman was identified as Siobhan Healy. She reportedly fell off of a ride called the Tip Top.
McFadden said that he had never had any problem with the ride in the five years he's been operating it. He said that it was possible the accident was captured by one of the CCTVs set up in the area.
Meanwhile, the National Police Service is investigating Healy's death, but a rep for the Health and Safety Authority says that they are not, as it did not appear to be a work-related accident.
Earlier in the evening, fans waiting to get into the show were caught in a heavy downpour that prompted severe weather warnings to be issued countywide.
Spears performed in Belfast, Northern Ireland, tonight and will play two shows in London this weekend.
