Ariana Grande got to work getting tickets into the hands of her real fans after she got fed up over insanely high prices for her tour tickets.

Sources connected to Ariana tell TMZ ... her team worked with Live Nation to correct the secondary sellers.

Ariana took to social media to say she was "bothered" by her 'Eternal Sunshine' tour selling out within minutes, only for scalpers to try and resell the tickets at jacked-up prices.

Our sources say Ariana is passionate about getting tickets to fans, and it was important for her to fix the ticket-scalping issues with her concerts. We're also told Ariana opted out of dynamic pricing so that tickets wouldn't spike in price if there was high demand and her team worked hard keeping tickets off the secondary market, which they were successful in doing.

Ticketmaster, which handled the ticket rollout, announced Wednesday, "Last October, we worked with the tour to cancel a portion of tickets that had been identified as violating our ticket purchase terms. Our focus is ensuring those tickets are reissued directly to fans, through a request process coming in February."

Take that, ticket-scalpers!!!
