Nearly 21 years after their '90s crime drama, Set It Off, Jada Pinkett Smith and Queen Latifah are reuniting on the big screen for Girls Trip, and only ET was on the set in New Orleans!

"I miss being with her onscreen," Smith tells ET's Kevin Frazier. "I was like, 'Why have we waited so long?'"

In the movie, four friends travel to NOLA for a fun weekend, but what starts off as a trip to rekindle sisterhood turns into rediscovering wild sides salacious enough to make The Big Easy blush.

"You're going to see some fights; you're going to see some dance battles; you're going to see some grown things," Pinkett Smith says.

"And some crazy stuff," Latifah chimes in. "Some ziplining that goes real bad over Bourbon Street. It's a lot."

And there was a lot going on in New Orleans during filming as well -- namely the Essence Music Festival. The festival, known as "the party with a purpose" is an annual event started in 1994, and last year featured artists like Mariah Carey, Maxwell, Kendrick Lamar and P. Diddy.

"We got to see some great performances," Pinkett Smith shares.

Joining Pinkett Smith and Latifah are Regina Hall and newcomer Tiffany Haddish, who took the veteran stars out on the town.

"Tiffany is the activities coordinator," Latifah notes.

Haddish even gave Pinkett Smith and her husband, Will Smith, some money-saving tips.

"She took Will and I on a swamp tour with the Groupon," Pinkett Smith says. "With Will Smith, mind you! I thought it was a coupon that she had for a group -- for us -- for a special tour. I didn't understand the idea of a Groupon, but I have learned. Tiffany has taught me so much on this trip."

"I'm teaching them how to save money even though they got it," Haddish explains.

While Haddish had plenty of fun off the set, actually performing with Pinkett Smith and Latifah was the biggest thrill for the young comedian.

"It's super fun and exciting," she admits. "When I say something funny and they laugh, I'm like 'Oh!'"

"The first two weeks that we were filming was like a dream come true for me, so I would go back to my hotel room and be crying, like, 'Thank you, Jesus! I can't believe this,'" Haddish adds. "And then I would call my girlfriends and be like, 'Yeah, I told y'all a** I was going to be working with them!'"

Girls Trip opens July 21.
