AceShowbiz - %cCeline Dion%, %cJennifer Lopez%, %cMariah Carey% and %cBackstreet Boys% are standing firm. They will not cancel their shows in Las Vegas despite an ISIS threat to hit the Strip following the bombing at %cAriana Grande%'s concert in Manchester.
Sources connected to Celine, J.Lo, Mariah and BSB tell TMZ that they have not wavered and their shows will proceed in the wake of an ISIS recruitment video soliciting lone wolf attacks on the Las Vegas Strip. Security will reportedly be ramped up in a big way.
Celine and J.Lo performed on Wednesday night, May 24 and they will perform again this weekend. The Backstreet Boys and Mariah, meanwhile, will perform next month.
Fans who want refunds because they are afraid to attend the shows will "likely" get a refund, according to sources at The Colosseum at Caesars, where Celine and Mariah will perform. As for J.Lo and BSB's fans, Planet Hollywood hasn't commented on the subject of refunds.
