ARIANA Grande took a stroll with ex-boyfriend Ricky Alvarez after calling off her New Years Eve show.

The pair looked at ease with each other as they walked to Starbucks on January 1, and the Get Well Soon singer looked snug in a huge Fendi jacket and a black face mask.

Her companion shielded himself from the cold in a beanie hat and oversized jacket.

Ariana’s appearance comes after she cancelled her New Years Eve concert in Las Vegas due to a case of bronchitis.

The star opted to stay with her family and friends instead of travelling across the country to perform.

Despite being spotted with Ricky, Ariana has told fans that she will stay single in 2019 after calling off her engagement to recent ex Pete Davidson.

The pop diva vowed that she would go it alone in a tweet to fans and said she wants to stay single for the rest of her life.

It comes after she and Saturday Night Live funnyman Pete’s relationship hit the rocks last year and her ex Mac Miller tragically died.

The pair had been engaged and the split was the basis for Ariana’s latest hit Thank U, Next.

A fan had tweeted her writing: “Who is Ariana dating NOW?!” to which the star replied: “Spoiler: for the rest of this year/probably my life: It’s no one.”

She then told her 59million followers: “Please refer back to this tweet for future questions.”

Earlier she had written a defiant message on New Year’s Eve hoping to put her heartache behind her.

She said: “Farewell 2018, you f***.

“I hope this new year brings you all much laughter, clarity and healing.”

But she also took the time to thank her loyal fans for helping her through her struggles. She added: “My timeline is beautiful rn. Proud of u all and the human beings you’re growing into. Happy nye! Continue to take care of / celebrate each other the way you always do.

“Happy to know u thru the internet & have u in my life. Our relationship is real and important to me. Love u.”
