The first ever Nickelodeon 'SLIMEFEST' made a record-breaking splash in Sydney on Saturday with two star studded, sublimely slimy music concerts!

Local boys Justice Crew started kicked off the show with their hit single 'Boom Boom' hyping up the crowd before Jessica Mauboy took the stage performing 'Inescapable' and her current hit from 'The Sapphires' soundtrack, 'Gotcha'.

Hosts Luke & Wyatt used the 'SLIME SPINNER' to determine the slime games of the night, starting off with 'Balloon Blitz' where kids teamed up to move giant balloons filled with flutter, feather and slime to celebs E-Man from Justice Crew, Jessica Mauboy, Brian McFadden and Charlotte Dawson who burst them with spikes onstage.

Stars continued to get slimed in 'Shooting Stars' where kid competition winners shot slime from a cannon at Reece Mastin, Johnny Ruffo, Rachael Finch and Tiffany Hall on the "splatwalk"!

Cody Simpson, Delta Goodrem, Rove McManus, Ruby Rose, Lisa Wilkinson and Karl Stefanovic appeared onscreen to support and introduce the new pro-social anti-bullying campaign 'Dare To Be Square' inspired by the one and only SpongeBob SquarePants.

Stan Walker debuted his new blonde locks, performing a rendition of 'Dynamite' onstage while photos of kids and celebrities "throwing a square in the air" flashed up on the big screen as kids in the audience made squares in the air too.

The most anticipated sliming of the night was voted by the crowd, with Commando Steve from 'The Biggest Loser' being dunked into a slime filled dunk tank, Nickelodeon’s first full-body slime submersion!

But the sliming didn’t stop there, with stars sliding down the giant 'Slip 'n Slime'!

The splash-tastic event also broke a Guinness World Record for "Most People Slimed Simultaneously" when over 3000 Aussie kids in the 'Sloshpit' were blasted with the giant 'SLIMEFEST-ATRON' periscope in a gooey green slime-storm!

Those at the second show were treated to a surprise performance from Guy Sebastian singing his feel-good hits 'Don’t Worry, Be Happy' and 'Gold'.

Between slimings, stars rocked the stage with Reece Mastin performing 'Shut Up And Kiss Me', 'Shout It Out', and 'Goodnight'. Johnny Ruffo sang 'On Top Of The World' and a cover of Carly Rae Jepsen's 'Call Me Maybe', while fellow 'X Factor' alum Christina Parie performed '16 And Unstoppable'. Stan Walker also slipped back onstage to perform 'Light It Up', 'Loud', and 'Music Won’t Break Your Heart'.

And of course, the show ended splash-tacularly, with kids and celebs sharing the joy of slime! If you could slime any celebrity, who would it be? Let us know by commenting below!
