The pair met back in 2016, when Ariana appeared on Saturday Night Live – on which comedian Pete is a cast member.
Whilst promoting her album Dangerous Woman, Ariana made an appearance on the late night variety show, Saturday Night Live.
At the start of May this year, Ariana confirmed her two year long relationship with fellow singer Mac Miller had ended after rumours began to circulate about her and Pete Davidson.
She confirmed the split on May, writing on Instagram, “This is one of my best friends in the whole world and favourite people on the planet.
“I respect and adore him endlessly and am grateful to have him in my life in any form at all times regardless of how our relationship changes or what the universe holds for both of us!”
According to TMZ, the pair parted ways this weekend after a difficult month for the singer.
Sources told the website it ‘simply wasn’t the right time for their relationship to take off’, but they still have lots of love for each other.
The pair officially confirmed the shock engagement news on June 16 when Pete uploaded a black and white picture to Instagram of the couple’s hands intertwined, with the ring clearly visible.
It’s been a tough few months for Ariana after her rapper ex Mac, who she dated for two years, died from a suspected overdose.
And the singer, who is currently taking some time off following his death, recently worried her fans when she tweeted a string of emotional messages and begged for “one OK day”.
The pop star told her 57.8million Twitter followers: “Can i pls have one okay day. Just one. pls. I’m so tired pls.”
