X Factor stars Union J are set planning a huge meet and greet in London tonight for their fans.
The boys - JJ, Jaymi, Josh and George - will be appearing at London's Brent Cross shopping centre in near the show's Wembley Studios from 6PM.
The group - who passed 300,000 Twitter followers yesterday - tweeted last night: "The info you have BEEN WAITING FOR! #MeetUnionJBrentCross shopping centre, London, TODAY at 6pm! Pass it on! Union J x"
They added: "#MeetUnionJBrentCross Shopping Centre, London! CAAAANT WAIT!!! George X"
With the trend #MeetUnionJ quickly topping the worldwide trend list, it seems that there will be no shortage of screaming teenage girls attending this evening's event!
The boys also revealed that they've been banned from meeting their fans outside the show's hotel.
The group, who have named their followers JCATS, said show bosses have ordered them to stay inside from now on.
George Shelley tweeted: "Who's outside the hotel? Really really want to come out and see you all but were not allowed! 🙁 George X"
And JJ added: "Really sorry but we won't be able to come and see all of you waiting outside the hotel tonight.. were flat out meetings ect... Much love JJx"
