Did I go see Jaden Smith on the off chance that Will would make an appearance?
Alas, Big Willie didnt show up but Jadendidplay Icon twice.

20-year-old Khalid hilariously forgetting his own lyrics.
Mere hours before the release of his long-awaited album, Travis Scott welcomed festivalgoers toAstroworld.
The Chicago crowd went wild for the entire 90-minute set well, almost everyone.
Early in his set, Scott allowed a fan to come up on stage.
Friday was a Post-filled day.
They also said theyve performed in Chicago before in front of zero people.
Im glad to report that their Lolla set had well over zero people.
Savage to those who were clearly camping out all day for the Congratulations rapper.
But the rapper delivered a set that lived up to the atmosphere.
Unsurprisingly, the true highlight of the weekend was Bruno Mars.
The singer closed down Fridays festivities with a firework-fueled dance party.
He also appeared to end his set before playing Uptown Funk.
Watching people leave right then was like seeing moviegoers leave a Marvel film before the end credits.
Like, have you ever seen a Marvel movie?
Of course, Mars came out to perform the hit song as an encore.
Unfortunately for him, everyone in the crowd were just referring to him as Clay.
LL also tried a little stand-up.
Isnt he with Chris ODonnell?'
17.Carly Rae Jepsen got a sword.
The Weeknd won out for your writer.
Maybe a name change to LL Cool ROC is in order?
Its 2 p.m. on Sunday in Chicago, do you know where your children are?
Well, they could be sneaking into Lollapalooza by running through an emergency exit gate.
Sunday was an evening of disappointingly short sets from rappers.
First up was Gucci Mane (or at leastwho we think was Gucci Mane).
Despite being scheduled for an hour, the Lemonade rapper performed for just 30 minutes.
23.Though Lil Uzi Vert didnt perform his full hour set, he still delivered a crowd pleasing performance.
He proceeded to throw the mic in the crowd before walking off.
Thousands, nay millions, of staged Instagram pics.
