Pop star Ariana Grande has paid tribute to Saffie Roussos, the youngest victim of the recent Manchester Arena bombing.

Saffie, who would have celebrated her ninth birthday on July 4, was among the 22 people killed at Grande’s Dangerous Woman Tour concert on May 22.

After performing in Buenos Aires on Wednesday, the “Side To Side” singer took to Twitter to pay her respects. “Saffie, we’re [thinking] of you baby” she posted alongside a birthday cake emoji.

Hundreds of people in Saffie’s hometown of Leyland, Lancashire gathered on Tuesday to mark the occasion.

Her father, Andrew, told the BBC that his daughter was “everything you could wish for in a little girl.” He continued: “She loved dancing, music, gymnastics. If she wanted something, she would do it.”

Saffie attended the concert with her 26-year-old sister Ashlee Bromwich and her mother Lisa, who is still recovering from injuries.

“She was Ariana Grande-obsessed,” Ashlee said in an interview with the BBC, “She kept on going, ‘come on Ashlee you promised me you’d get up and dance’ – so we had a little dance. She was so happy, she was elated all night, grinning.”

Grande, who organized the One Love Manchester concert which raised over £2m for the victims of the terror attack, is in line to receive honourary citizenship of Manchester in plans put forward by the city council.
