Let's take a look:
The event kicked off with a performance by Rappers Abra, Loonie, Ron Henley and the Lyrically Deranged Poets (LDP).
The fans went crazy when vloggers Thatcher Joe (aka Joe Sugg), Caspar Lee and Oli White went onstage (fans call them #Jaspoli).
They started with a game called 'Mr' & 'Mr' which they announced on their twitter accounts earlier, asking fans to throw them "Who would most likely" questions. They answered some of the question onstage.
Bogart the Explorer also came out to help teach them Filipino. He taught them how to say "Magandang araw po sa inyong lahat" (good day to you all), which drove the crowd wild.
Here's a cute IG post from Bogart, who brought #Jaspoli letters from Pinoy fans who didn't get to see them:

Kristine of Real Asian Beauty was up next, helping a fan with a makeover.
Next, Chicser, which had fans of all ages jumping and shouting for them:
Lloyd Cadena went onstage for a "Stik-O challenge" for his fellow YouYube stars – who could stuff the most number of sticks in his mouth? Oliver won and received a crown made of Stik-O.
Mich Liggayu came out next with an upbeat dance number.
Jireh Lim sang his hit song "Magkabilang Mundo." After that, he took a lucky fan onstage and serenaded her with "All Of Me."
Allstar Productions followed with their number.
Bogart the Explorer came out next and surprised everyone with his mad drum skills (Marco Ho, who plays Bogart, is the drummer of Giniling Festival). He had a drum showdown with the host Dominic James Lau.
This was followed by social media sweetheart Donnalyn Bartolome, who performed her rendition of "Super Bass."
Bethany Mota and Apl.de.ap were up next – Bethany told everyone how Apl toured her around Intramuros and said she loved halo-halo.
Apl.de.ap performed "Breathe" with former The Voice contestant Jessica Reynoso. After that, Loonie and Abra joined them and sang "Where is the love."
AJ Rafael performed next, getting the crowd swaying and waving with their phones.
