Devoted fans of the actress are urging that a individual who breached a fence and touched the actress during the recent Wicked: For Good debut be arrested or deported from Singapore.
A viral footage depicts the Australian man shoving aside camera operators and lunging at Grande while the performers made its way down a event pathway accompanied by supporters.
Fellow actress Cynthia Erivo promptly guided the stunned performer away from Mr Wen, who was observed being escorted out of the premiere by event staff.
Mr Wen posted on Instagram late on Thursday that he was "let go after being detained", though official papers indicated that he was scheduled to appear on the following morning. It is unknown if he was formally accused.
This is not the first time for Mr Wen, who calls himself a "Notorious Troublemaker", has invaded a performance. His Instagram account features clips of him interrupting other star-studded functions, including rushing the platform at Katy Perry's Sydney show in earlier this year and in a similar way during The Chainsmokers performance in the city last December.
"Steps should be implemented enforced against him as this is evidently a criminal offence," commented an Instagram user, in a reply to a video Mr Wen shared of his behavior.
"You've done this repeatedly... how are you not behind bars?" a different Instagram user remarked.
Several supporters criticized Mr Wen for "causing further distress" Grande, who had spoken of experiencing trauma-related anxiety after a devastating incident at the end of her 2017 performance in Manchester, resulting in the death of 22 people and harming numerous individuals.
"Ariana has been through so many scary things... and at her Manchester concert and you thought it would be fun to jump the barricade?" said a further response on Instagram.
Several attendees also faulted event staff at the premiere for not being adequately prepared; while some requested online networks to block Mr Wen's content.
In clips shared widely, Grande appeared surprised when she was touched by the intruder. Her co-stars Michelle Yeoh and Erivo can be spotted reassuring her while Mr Wen was led out by security.
Grande has remained silent on the incident, and the premiere activities carried on uninterrupted.
Many of supporters had gathered in a sea of green and pink at the Wicked: For Good Asia-Pacific premiere in a Singapore mall, including a number who had stood in line for as long as a significant duration before it began.
The film, to be launched on the 21st of November, is the sequel of a two-part adaptation of the well-known theatrical production Wicked, which focuses on the unlikely relationship between two distinct sorceresses.
The musical itself is a derivative of the classic children's novel The Wonderful Wizard of Oz.
Grande, who acts as the good witch Glinda, was decked out in a champagne pink sequin dress at the event while Erivo, who plays the villainous character, wore a sleek black dress embroidered with roses.
They were joined by fellow actor Jeff Goldblum.
The initial film, Wicked, was the top-earning motion picture of the previous year in the UK, and earned ten award recognitions, earning several for best costume and artistic direction.
