Take a look inside Bella Thorne's Coachella after-party featuring Diplo, Big Sean, and 15 pounds of weed

The exclusive soirée, which Thorne began planning in November, was located a short drive from the festival in Bermuda Dunes.

"Because of everything with Covid, we started planning later in the year than we really wanted to, just because we needed to know if Coachella and any events were going to happen this year," event director Michael Cohen told Insider.

His team at Infused Group got the go-ahead in October when Coachella announced that it would no longer require proof of vaccination to attend.

The "Shake It" singer said she plans to continue hosting the event to make it more elaborate and exciting each year.

"Our whole original vision for this was, in the next four to five years, we want to be able to compete with Neon Carnival," Cohen agreed.

"This was our third event myself and Bella did together. Next year, we are going to go even bigger," he added.

Thorne said she was spurred to go with an alien theme because her sister reminds her of "a little mini alien."

"And we were in the desert, so it fit really well," Cohen added.

Cohen said the Drip Dome was a last-minute addition to the party because they had a major vendor fall through, adding that it was a big hit for Instagram photos and other forms of content creation.

Every year at Coachella, there's a variety of branded events and after-parties that celebrities and VIP guests are invited to attend. But as Cohen noted, it's rare for a celebrity to be hosting one alone.

"Everything else is like, a big Revolve party," he told Insider. "So I was like, 'Bella, you could do this and you could be the only person, like a singular individual of this stature, to really pull something off like this.'"

"Overall, compared to all the other parties we attended this past weekend, ours felt the most authentic," he added. "It was a grassroots event at the end of the day. The only goal was to create an unparalleled experience for our attendees."

Thorne launched Forbidden Flowers in October 2019 in conjunction with Glass House Group, a fast-growing cannabis company.

Her party boasted a massive art car by Rynobus — or "huge smoking bus," as Thorne called it — so guests could play video games and smoke marijuana in peace.

"People were staying in there the entire event so I was like, yeah, that's awesome," he said.

"We were just like, 'Everybody smoke, smoke here, smoke there, smoke!' It was amazing," she told Insider. "It's always great when you walk home with weed from a party."

The popular YouTuber and influencer, who previously dated Thorne, was one of many famous attendees.

According to Cohen, his team originally envisioned a 400-person cap, but they ended up welcoming about 500. He said the invite-only event was designed to minimize a "fan presence."

Thorne also said she specifically asked people not to take unwanted photos of her guests or "be in their face."

"I just don't want anybody feeling like that at my party," she told Insider.

"Bertha goes around in all the really big festivals, mainly Burning Man," Cohen explained. "During all these festivals, people bring different gifts to Bertha, and Bertha is supposed to grow, figuratively, and change colors."

"The community of Bertha is kind of worldwide," he added.

Thorne said she emphasized the importance of sound quality during the planning phase.

"I knew that the stage production was one of the most important things so that our artists felt comfortable, and that everything was right for them so that they could put on their best performance," Thorne told Insider.

"Sometimes you have some sound issues. They even have them at Coachella," she continued. "And we didn't have any production issues. That made me so, so happy."

The American DJ and producer had just come from a surprise set at Coachella's Do LaB stage.

"When we were curating the lineup, we really wanted to get people who were good in the party scene," Cohen told Insider. "Also, Bella and Diplo have a really good relationship. So we thought he would be the perfect person to get."

"He was really excited about it all too," Cohen added. "He had a really great time."

"Nobody knew Big Sean was going to come out, so that definitely set a tone," Thorne told Insider.

"People just started running, like a fucking mob, running, just going so fast as soon as they heard him from the speakers," she continued, describing the moment as "euphoric."

"But what made me so happy was seeing everybody else have a fucking blast," Thorne told Insider.

"I was definitely working, couldn't really say hi to many people, and that's OK," she continued. "But so many people texted me that they had just the best fucking time, so that made me excited."
