Ballerini, 24, kicked off the weekend by flying to Las Vegas with some of her closest friends by her side.
Wearing a “Feyoncé” top Ballerini posted a video from the trip where she paid homage to Kristen Wiig’s character in Bridesmaids.
“I’m ready to party with the best of ‘em,” she said in her best Wiig impression, which she captioned with her special bachelorette hashtag: #KBMETHERMATE.
After they landed, Ballerini and her friends went to check out Lopez’s Planet Hollywood show. But not before they got some pictures with the iconic singer.
“Don’t be fooled by the rock(s) that I got,” Ballerini captioned her selfie with Lopez.
She also shared a goofy group photo featuring Lopez and all of her friends.
And to cap it all off, Ballerini posted a picture that was just of her and her girls.
Wearing matching “Bride Squad” bathing suits, Ballerini cheekily captioned the photo, “friends that have matching wedgies together stay together.”
On Christmas Day 2016, Ballerini, 25, announced she was engaged to Australian country singer Morgan Evans.
“On March 12th I met and hosted an awards show with @morganevansmusic…” Ballerini wrote on Instagram, sharing a video of the couple’s onstage banter at Australia’s Country Music Channel Awards earlier this year.
“This morning, 9 months and 13 days later, he got down on one knee in the kitchen while I was burning pancakes and asked me to marry him. Loving him has been the greatest gift of my life. And now I get to do it for life. #HECALLEDDIBS”
The “Love Me Like You Mean It” singer added on Twitter, “I GET TO MARRY MY AUSSIE. My heart is bursting from loving this human so much. Luckiest girl in the world.”
In January Ballerini told PEOPLE she hadn’t started planning the wedding yet — not even to pick the date.
“This year’s so hectic with music that, I don’t know, I don’t think it’ll be a big priority for us quite yet,” Ballerini said.

But in July, the bride-to-be told PEOPLE she’d not only picked a date, but she’d also said yes to the dress.
“My momma and closest friends surprised me with a fitting, and I said yes to the dress with the other loves of my life,” Ballerini added.
