India, Nov. 15 -- American singer-actor Ariana Grande was accosted at the Wicked: For Good premiere at Universal Studios, Singapore, on November 13, and the man responsible later bragged about it online. Shortly after the unfortunate incident, fans identified him as 25-year-old Australian influencer Johnson Wen, known as "Pyjama Man". He even posted a video of the moment on his personal social media account, captioning it: "Dear Ariana Grande, thank you for letting me jump on the yellow carpet with you." The 32-year-old had been walking the carpet with co-stars, actors Michelle Yeoh, Cynthia Erivo and Jeff Goldblum when Wen sprinted towards her, turned her around and grabbed her. Videos show him putting his arm around Ariana and pulling her close as she tried to step away. Erivo, who plays Elphaba, instantly intervened, positioning herself between Ariana and the man. Security removed him within seconds as Ariana appeared visibly shaken, with Cynthia and Michelle staying by her side. This isn't Wen's first such stunt. In June, he jumped onstage during a Katy Perry (American singer-songwriter) performance; in August, he tried to crash Canadian singer and songwriter The Weeknd's show before being dragged off by security. Bizarrely, he has attempted a similar stunt on Indian cricketer Virat Kohli as well. htc...
