News broke earlier this week that the couple had called off their engagement. While it was widely reported that the couple had gone their separate ways, a source has since claimed they've simply slowed things down.
But neither of the stars have clarified exactly what's going on between them.
And Ariana was seen for the first time since the news broke on Tuesday night as she took to the stage with a special musical performance, although she admitted that her anxiety almost stopped her from doing it.
Dressed in green, the 25-year-old took to the stage to perform song The Wizard and I from musical Wicked.
She also shared selfies from behind the scenes.
Adding a caption to one of the pictures, she said: "can't believe I almost let my anxiety ruin this for me today!!!! not today satan! not tomorrow or the next day either not no more u can suck my big green d**k imma sing my heart out and be a big walking vessel of love bye"
The star had promised fans that she'd still take part in the show despite her relationship drama.
Sharing a script that showed which song she'd be singing, she said: "honored to be included in this celebration of 15 years of my favorite musical of all time wouldn’t miss it for the whole universe #wicked15"
Meanwhile, TMZ reports that Saturday Night Live star Pete has cancelled a headline comedy gig on Wednesday night.
He was due to perform at Temple University, but is said to have dropped out at the last minute and been replaced by Pitch Perfect star Adam DeVine.
It comes after a source told People that while Ariana and Pete's engagement was off, they hadn't split for good.
