Selena Gomez Concert Tickets?

Ok so Selena Gomez Meet & Greet tickets are available tomorrow! And i'm 14 and it says "all people under 15 need to be accompanied by an adult". The price for the meet and greet is £95 and i was wondering. Do i have to buy an adult ticket aswell for my accompanier? I dont think i will need too because it seems unfair that 15 year old's only have to pay £95 whereas under 15's have to pay £190 for an extra ticket jsust because we have too! So yeah, from personal experience, will I need to pay for my adult accompanier's ticket? Thanks. (btw im using ticketmaster)
