The two split earlier this year and Grande moved onto a whirlwind romance with Saturday Night Live comedian, Pete Davidson, in May. The pair got engaged in June, but news broke last week that they had split.
“Protect your peace, get rid of toxicity, cleanse your space, cultivate love,” she wrote.
A day earlier, Davidson, 24, addressed their break up for the first time during a comedy show with Judd Apatow at Largo at the Coronet in Los Angeles, California, joking about having to move out of the New York City apartment he and Grande were living in.
"As you could tell, I don't want to be here. There's a lot going on," he told the audience, according to multiple outlets. "Does anybody have any open rooms? Looking for a roommate?"
Meanwhile, Grande's brother, Frankie, is continuing to show his support for his sister, visiting her in the studio and sharing a cute family pic on Monday.
"Visiting my sister in the studio with my mommy and my nonna," he wrote. "These are the three strongest women i know... and i cherish them with all of my heart. 💕 it’s good to be home. 🏠 #goGRANDEorgohome."
