Jennifer Lopez has announced that she will not perform her next three scheduled shows in Las Vegas on Wednesday, 10/4, Friday, 10/6 & Saturday, 10/7, according to Variety. The cancellations follow the tragic mass shooting that took place at Route 91 Harvest Festival in the city this Sunday.

The triple-threat actress, singer, and dancer is currently performing “Jennifer Lopez: All I Have” concerts as part of a Las Vegas residency at the Planet Hollywood Resort and Casino.

“Jennifer is heartbroken that such a senseless tragedy occurred,” reads a statement announcing the cancellations. “Her thoughts and prayers are with the victims and their families.” Jennifer responded to the news with the following tweets:

Cirque Du Soleil and Blue Man Group also chose not to perform on Monday night out of respect for victims of the attack, along with all shows at MGM Resorts properties on Monday and Tuesday nights. A spokesperson from Caesars Palace confirmed that all Monday night shows at that venue and all Caesars Entertainment properties were cancelled as well.

The statement from Jennifer Lopez informs ticket holders for this week’s shows that they can expect to be contacted by Ticketmaster and the Axis box office to issue refunds or exchanges for any other on-sale performance of “Jennifer Lopez: All I Have” from February 21 through June 9, 2018.
