Any of the gripes people had with Justin Bieber's weekend one performance disappeared like so many stars into the Indio sky Saturday night (4/18) during his second weekend set.

And the best, most tender, most relatable moment wasn't even a duet or a collab, it was a former lonely girl, who was pushed on stage to stumble her way to her childhood crush, who was then hugged and serenaded by JB.

As you may have heard by now, because it's zooming around every corner of the web, in the middle of Act III of Bieber's three act set, longtime Belieber Billie Eilish made it on stage, not to sing, and embodied many of the wildest dreams of the 125k there at the Empire Polo Club.

The fun started at the end of the first act when Justin and Sexyy Red lived up to our prediction from 4/3 and live debuted "Sweet Spot" together.

What the Coachella stream on YouTube didn't pick up was how the audience that stretched far back into the field were singing along to both Justin and Red's verses.

This might be a surprise to those who have only read the comments on the official video of so-called fans who seem to hate Red's participation on the Swag tune.

The Bieber fans who made the trek to the desert and paid the money loved her surprise appearance.

Meanwhile the fans who spent all day in the heat holding their positions on the rail loved the fact that Justin went down to receive their adoration during the second song of the night, "Speed Demon" from Swag II.

He returned to the super fans in the front row for the final tune, "DAISIES," from the first Swag. For some reason they all loved that too.

After a half dozen new songs from the two Swag LPs, done acoustically, ending with the very sweet "Everything Hallelujah," Justin did a few of the old hits the fans had been begging for.

These were done in the style of weekend one where he pulled them up from YouTube and sang along. The crowd ate it up.

"I just feel like there's so many songs I want you guys to experience," Justin said as he typed in "One Less Lonely Girl" into the YouTube search box and then sang to the video.

As the younger JB performed on the screen behind him, adult Justin sang to the crowd and the camera on stage. When the bridge began the camera caught what first appeared to be a fan either being pushed or climbing the stage.

As it played out, it was soon obvious it was Billie Eilish who had been "pushed" by her sister-in-law.

When she finally made it to her long time crush, he embraced her and tried to comfort her as she was freaking out in the most adorable way ever.

Once Billie left, Big Sean appeared to do two songs, "As Long as You Love Me" which hadn't been performed for nine year, and "No Pressure."

Sean also delivered a touching speech to both the crowd and to his long time friend, telling him, “you dedicated your whole life to this.”

And if all of that wasn't enough to give the attendees of weekend one the worst FOMO, SZA popped up to do her song "Snooze" with her.

The last time the pair performed it together was during the Grand National Tour last year when SZA brought Justin up in LA's SoFi Stadium.

So what's next for Justin? As he was wrapping up his show he told the crowd, "I'll see you all soon."

Is he hinting at a Swag Tour? Despite playing soooo many songs from those new albums, many of those in attendance were satisfied just to see Justin healthy, happy, and belting out even a few of those older bangers.
