Just a few days ago, MAMAMOO announced their very first fan meeting, '1st MOO Party,' to the excitement of fans!  Truly showing the immense popularity they're enjoying for a rookie girl group, MAMAMOO has expressed their gratitude because the tickets are sold out!

What's most impressive is that the event sold out of tickets within one minute of opening sales.  Whoa, we have a new girl group to watch out for regarding ticket power.

The event will be taking place on August 25 at the Seoul Olympic Park's Woori Financial Art Hall.  On the night of the 5, the exclusive ticket sales began through Inter Park at 8 PM. A minute later, all tickets for 1,184 seats were sold out.

Those lucky people who got ahold of tickets will get to hang out with these quirky girls for two hours, watching never-before-seen videos and performances and more!
