A 31-year-old woman was killed when she fell from a fairground ride set up right outside Dublin's O2 arena after a Britney Spears concert there Monday.
The singer took the news particularly hard.
"I was saddened to hear of the tragic accident in Dublin. My heart goes out to the family. - Britney," Spears personally tweeted after the incident.
"We can't say [what happened], it all happened so quick," Kenneth McFadden, owner of fair operator McFadden Entertainment, told Dublin's Independent.
"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. The National Police Service is investigating Healy's death.
Britney Spears performed in Belfast, Northern Ireland, Tuesday and will play two shows in London this weekend as her Femme Fatale tour rolls through Europe.
