A day after an out-of-control crowd clashed with police outside a film premiere, security is being beefed up ahead of a Lady Gaga concert in Hollywood Thursday night.

Fire Battalion Chief Michel Bowman says he’s doubling the number of fire inspectors at Thursday evening’s event to monitor the size of the crowd.

He said 2,000 fans have been permitted to attend a taping of the concert behind the “Jimmy Kimmel Live” studio. The show is doubling its security staff and paying for the extra fire personnel.

A film premiere and block party attracted hundreds of electronic music fans to the same area Wednesday, resulting in an unruly crowd that clashed with police in riot gear.

Police Cmdr. Andy Smith says there will be extra officers to prevent a repeat of Wednesday’s disturbance.
