Think prosecco, cocktails, food and not a pair of sweatpants in sight: a Mean Girls-themed brunch will happen in Sydney some time in April.

The cult-classic film, about high-schooler Cady Heron (Lindsay Lohan) who accidentally falls in with an elite group of popular girls dubbed "the Plastics", will be screening in the background.

Guests are encouraged to dress up for the occasion. The dress code? You guessed it: pink.

More information and pre-release tickets here. Honestly, we're surprised they didn't wait until October 3.
