Ariana Grande reunites NSYNC at Coachella – but Justin Timberlake skips the show

ARIANA Grande reunited most of NSYNC onstage at Coachella last night - but Justin Timberlake skipped the show.

The singer, who headlined the California festival on Sunday night, was joined by JC Chasez, Joey Fatone, Lance Bass and Chris Kirkpatrick after she performed Break Up With Your Girlfriend I’m Bored.

Justin was missing fro the festivities as he had just wrapped up his 115-show Man of the Woods tour.

Ariana said: "I've been rehearsing my whole f***ing life for this moment!"

Grande and the boys then launched into a rendition of their hit single Tearin Up My Heart.

Ariana's set also included guest appearances from Nicki Minaj, Diddy and Mase.

It comes after the star revealed the effect post-traumatic stress disorder has had on her brain following the Manchester Arena bombing.

The singer, 25, has been battling the condition since her concert was targeted by terrorists in 2017.

Raising awareness of how PTSD can affect the brain, Ariana shared her recent brain scan on Instagram.

The image showed three brain scans, one of which was the chart-topper's own.

The first graphic showed a healthy brain and the brain of somebody suffering from PTSD side by side.

Ariana then revealed her own scan which showed double the amount of PTSD activity using a highlighting technique.

She wrote across the snap: "Hilarious and terrifying," before bluntly adding: "Not a joke."

The Thank U, Next star has been open about her battle with PTSD and anxiety following the horrific terror attack on her Manchester concert that killed 22 people in May 2017.

While her music career has continued to flourish, Ariana has admitted life behind-the-scenes has been tough and recently told British Vogue the bombing is "very much" still with her.

She has complained of dizziness since the attack, adding: "That's what everyone was telling me. It's hard to talk about because so many people have suffered such severe, tremendous loss.

"But, yeah, it's a real thing. I know those families and my fans, and everyone there experienced a tremendous amount of it as well."

Ariana went on to admit that she still can't talk about the attack without crying and getting upset.

She said: "Time is the biggest thing. I feel like I shouldn't even be talking about my own experience - like I shouldn't even say anything."
