5 Seconds of Summer's Michael Clifford has been having treatment for "mental health problems".
The 19-year-old guitarist revealed during the group's gig in Auburn Hills, Michigan, earlier this week that he had sought help from a therapist during a break in their Rock Out With Your Socks Out tour, though he didn't give any details about his condition.
He told the audience: "I was fixing some problems with my mental health.
"I just saw a therapist real quick on the break we had. Anyways, I'm going to shut up now. We're gonna play another song if it's OK?"
After the concert finished, #WeLoveYouMichael began trending on social media, while Michael was also flooded with messages of support from the group's devoted fans.
