So Ariana pulled through last night in Atlanta and put on one hell of a show. She must have been feeling much better as fans were giddy from her rocking the stage like no other at State Farm Arena last night. The performance was full of surprises including Liz Gillies and Ariana Grande singing together on stage and it was honestly adorable.\nWe all remember Ariana's feeble beginnings as a child star on Nickelodeon's Victorious back in the day. Her iconic (and honestly sort of obnoxious) voice as Cat will never be forgotten, but she has had quite the turn-around because she arguably has the best singing voice in the universe. She definitely showed that off last night in Atlanta.\nThe cutest thing ever happened in a whirlwind of nostalgia as Victorious co-star, Liz Gillies joined Ariana on stage to sing a duet of "Give It Up" from their hit Nickeloden show.\n9 YEARS LATER .. YALL STILL GOT IT pic.twitter.com/UHfWrwjGa0— carli (@aIrightave) November 20, 2019\nCat (Ariana Grande) and Jade (Elizabeth Gillies) joined forces six years later, and it was iconic. The two have a close relationship and were both grateful for last night's reunion. A trip down memory lane for all.\nthe most special show to me yet. truly. love u. this was too much to process and don’t know what to say yet but so grateful and thrilled. love u forever @LizGillies @MattBennett.— Ariana Grande (@ArianaGrande) November 20, 2019\nFans were flipping out when the two of them took the stage to show of their immense talent and it was literally everything.\ni’ve never been so grateful. seeing you all so happy tonight brought me so much joy n comfort. i love you. thank u for making this year so unbelievably special. u really are my whole heart 🥺🖤.— fiona grande (@arisdailyupdate) November 20, 2019\nThat's not the only one who joined the pop legend on stage, though. Another Victorious co-star, Matt Bennett, took the stage to sing a song that he once serenaded Cat with on the show.\nHe played a beautiful acoustic melody on his guitar while singing "I Think You're Swell," claiming that he wrote it "ten years ago for a very special girl" and was so lucky to be able to perform it on stage. He even hinted at it on Twitter the night of the concert!\nIs it because you think Atlanta's swell?— Matt Bennett (@MattBennett) November 19, 2019\nAriana told fans at the concert that Atlanta was her favorite show on tour because of her special guests and former co-stars!\nAs many fans probably know, Ariana has been battling an illness for quite some time, making it hard for her to breathe on stage. She is super dedicated to her fans though and really pushed through last night, just like the baddie she is.\nThere are stories everywhere!
