It comes after Cruz became emotional on stage during a gig on Tuesday while performing his group's new song Loneliest Boy - understood to be filled with barely veiled references to his wayward brother Brooklyn's continued absence.
With brother Romeo and supportive parents David and watching from the audience, Cruz faltered over the song's plaintive lyrics, prompting band-member Dan Ewins to drape a reassuring arm across his shoulders.

Earlier this month, older brother Brooklyn dealt another blow to his devastated parents as he failed to mention Victoria on Mother's Day, though praised his mother-in-law on social media.
Looking on from their seats at the tiny east London venue, his family members were visibly moved by the performance, with Romeo seen wiping away a tear as he looked up at the stage.
One concert-goer told The Mirror: 'At one point during the song, he seemed overcome with emotion as his bandmate put his arm around his shoulder and affectionately ruffled his hair.'
Fans have been left convinced that the song is about Brooklyn's widening estrangement from his family.
Additional lyrics read: 'It shows in the small things that you don't do, I guess in the end that it's you, yourself, and you. Tell me how do you live, when you've got nobody to lose?
'Loneliest boy, place all your bets on him, To find something bad in somebody good, he always does, Loneliest boy, I hope that you’re listening, Don’t push all your friends away, when we’re tryna show you love.'
Elsewhere, the chorus reads: 'So tell me you’re scared, and that you need someone to hold. Cause you’re in the room but really, does it even show?
'But, why can’t they see that you’re a million miles away, They’ll never know, when you look so close.'
