The cast of the upcoming adaptation of "Wicked" has been in Sydney to promote the film, with a video of Ethan Slater going viral.

Ariana Grande and Ethan Slater — who both star in “Wicked” — showed sweet PDA at the film’s Los Angeles premiere. The pop star was a doting girlfriend as she adjusted Slater’s bow tie on the star-studded red carpet Saturday. Grande, 31, was all smiles during the cute moment as she made sure her beau was camera-ready.

According to Daily Mail, Universal execs were “worried” that their love affair scandal would overshadow Wicked’s success. The movie-musical is a two-part bonanza, with the first film reportedly costing $145 million USD (approximately $220 million AUD) to make.

Ariana Grande has been very busy over the last few years as she released a new album and dedicated many months to filming the two-part film adaptation of the hit musical Wicked. While on set, she met co-star Ethan Slater, who plays the Munchkin Boq. Grande and Slater started off as friends and later fell in love.

Ariana Grande is “very happy” the world is getting to know her “amazing” boyfriend Ethan Slater. The “Sweetener” singer couldn’t help but gush over her new beau at the Los Angeles premiere of “Wicked” on Saturday as the two shared another sweet moment on the red carpet.
