Bruno Mars fans were left fuming as they found themselves locked out of Los Angeles' $2billion Intuit Dome arena due to a ticket scanner debacle on Thursday night,DailyMail.com can exclusively reveal.

Mars' concert — the first of two back-to-back shows — marked the official opening of the brand new indoor arena in Inglewood,California self-financed by Microsoft CEO Steve Ballmer.

But the night started off with a major hiccup as a technical issue with the Intuit Dome's ticketing system — which relies on impressive facial recognition software — brought entry to a standstill.

Video obtained by DailyMail.com showed thousands of concerned attendees packed tightly outside the 18,000-seat arena.

Many ticket holders also claimed they were having issues transferring their tickets from Ticketmaster to the Intuit app,which is required for entry.

Before the Intuit Dome,the Clippers had been playing at Staples Center,also the home of the Los Angeles Lakers and the NHL's Los Angeles Kings.

Ballmer — who originally didn't want to build an arena when he bought the team — wound up beginning to plot a Clippers-only home years ago and formally unveiled the project in 2019,saying then that the Clippers would break ground in 2021 and open in 2024.

'We don't want to play in anybody's shadow,' Ballmer said.
