wrapped up her promotional Dive Bar Tour on Thursday at The Satellite in Los Angeles, and ET was inside the wild, rowdy concert.
Gaga -- who used the three-stop tour, sponsored by Bud Light, to promote her new album Joanne
-- didn’t reveal the location of Thursday's show until close to show time.
However, that didn’t keep some of her celeb fans from turning up for the special, intimate event (which also included a bubble machine in the audience and a disco ball).
Ashlee Simpson and husband Evan Ross, Jamie Chung and Oscar winner Brie Larson were among some of the stars who showed up to listen to Gaga's rocking new tracks.
Gaga kicked the show off by walking through the audience singing "Come to Mama" on a wireless mic as she made her way to the stage with her back-up dancers, who rocked custom Joanne jackets.
Stripping down to a more shimmering ensemble, Gaga transitioned into her hit single "A-Yo,"
which set the rocking tone for the rest of her wild performance. She was also joined on stage by Mark Ronson, who collaborated with Gaga on several of the album's tracks.
While the show had its fair share in raucous moments -- including Gaga pouring a beer all over herself and some truly impressive dive-bar stage styles -- it also included a few emotional moments.
Before singing "Angel Down," Gaga took a moment to talk about the importance of love and respect, especially in today's tumultuous political climate.
“I wrote this song about people loving each other and taking care of each other," Gaga said to the crowd. "The election is coming up and I really hope that is a peaceful day, as much as it can be. I pray that on that day we all understand that not everybody is gonna vote for the same person. Everybody has different ideas and thoughts and that’s okay. We don’t have to hate each other because of that."
"What we have to do is come together," she added. "The reason is because there are a lot of people suffering and there are too many angels down, so let’s not focus on the hate, lets focus on who needs help."
Later, before singing the album's title track, Gaga opened up about how much the song meant to her, and the impact the album had on her relationship with her dad.
"After this record came out and everybody heard this music and came to my father's restaurant in New York to celebrate, I saw a look in my dad's eyes that I've never seen in my whole life," she shared. "Because when my dad was really young he lost his sister, Joanne, and sometimes I used to wonder if I got to meet my real dad.
Because sometimes things happen that are so hard in your life you die too, or a part of you dies. And after this record came out, I swear that a part of my dad came back to life."
During the high-energy rock ballad, Gaga went old-school rock star and jumped out into the audience, where she flawlessly performed the song while crowd surfing across her screaming fans. It's hard to finish a dive bar performance any better than that.
