Pop star Ariana Grande has teased the release of her first new music since the Manchester Arena attack.
The singer posted a cryptic upside-down tweet and three Instagram posts suggesting a new single, No Tears Left To Cry, will be released on Friday.
It comes just over a month before the first anniversary of the Islamist terror attack during Grande's concert last year, in which 22 people died and more than 500 were injured.
Her tweet had more than 217,000 retweets less than a day after she posted it on Tuesday night.
The 24-year-old star last tweeted and Instagrammed on New Year's Day, when she said: "See you next year."
It was accompanied by an audio teaser of music she was working on.
On her Instagram page on Tuesday, she posted a series of three pictures which made up the words No Tears Left to Cry 4.20, but upside down.

She also tweeted a tear drop and the words "missed you".
Grande became Manchester's first honorary citizen for her response to the bombing, after organising the One Love Manchester concert just two weeks on from the attack.
She got numerous other stars, including Katy Perry, Justin Bieber and Manchester's own Liam Gallagher, to sing in tribute to the victims.
The concert raised about £3m for the We Love Manchester Emergency Fund.
In the days after the attack, she also visited survivors in hospital.
