Loyal fans of the pop star are calling for that a man who breached a barricade and grabbed the celebrity during yesterday's Wicked: For Good debut be detained or deported from Singapore.
A widely shared footage depicts the individual from Australia bypassing camera operators and rushing toward Grande while the actors walked down a promenade accompanied by supporters.
Fellow actress Cynthia Erivo immediately pulled the shocked performer away from Mr Wen, who was observed being led away of the event by guards.
Mr Wen shared on Instagram Thursday evening that he was "released after being taken in", though legal records revealed that he was due to attend court on the following morning. It is uncertain if he was faced legal action.
This is not an isolated incident for Mr Wen, who describes himself as a "Notorious Troublemaker", has disrupted a performance. His Instagram feed includes videos of him disturbing other high-profile occasions, including rushing the platform at the artist's Sydney show in June this year and in a similar way during The Chainsmokers concert in the area last December.
"There needs to be action applied against him as this is evidently a legal violation," wrote an Instagram follower, in a response to a video Mr Wen posted of his actions.
"This appears to be a habit... why are you not imprisoned?" a different Instagram user questioned.
Several followers blamed Mr Wen for "causing further distress" Grande, who had spoken of suffering from trauma-related anxiety after a terrorist explosion at the conclusion of her 2017 concert in Manchester, claiming the lives of 22 people and wounding many.
"After everything she's faced... including the Manchester attack, you considered it entertaining to rush the barrier?" commented one more comment on Instagram.
Some fans also faulted security officers at the Thursday event for not being adequately prepared; while different individuals called for online networks to ban Mr Wen's uploads.
In clips shared widely, Grande seemed surprised when she was approached by the intruder. Her fellow actors Michelle Yeoh and Erivo can be spotted consoling her while Mr Wen was led out by security.
Grande has not issued a statement on the incident, and the premiere activities continued without further issues.
Many of fans had gathered in a crowd of green and pink at the Wicked: For Good international debut in a Singapore venue, including several who had waited for as long as eight hours before it began.
The film, to be released on 21 November, is the second of a two-film interpretation of the acclaimed theatrical show Wicked, which revolves around the unexpected bond between two contrasting witches.
The musical itself is a spin-off of the twentieth-century children's novel The Wonderful Wizard of Oz.
Grande, who portrays the benevolent sorceress Glinda, was dressed in a champagne pink sequin dress at the event while Erivo, who portrays the Elphaba, wore a sleek black dress featuring roses.
They were accompanied by cast member Jeff Goldblum.
The first movie, Wicked, was the most successful motion picture of last year in the UK, and received 10 Oscar nominations, securing a pair for excellent wardrobe and production design.
