Ariana Grande and her actor boyfriend Ethan Slater put on a loved-up display in Sydney

Ariana Grande and her actor boyfriend Ethan Slater put on a loved-up display in Sydney on Tuesday, as they attended a photocall to promote their new movie Wicked.

The pop star, 31, was spotted tenderly hugging her co-star boyfriend Ethan, 32, as they posed up a storm in front of a world famous Sydney attraction.

The Florida-born singer looked absolutely radiant as she rocked her best angles in a custom-made pink Vivienne Westwood gown, which featured a frilled hem and lace trim.

The figure-hugging gown showcased the singer's slender figure and flawless skin. She completed her look with eye-popping white heels.

Her brunette hair was pulled back in a bun and a light layer of nude make-up helped highlight her natural beauty.

Ariana was seen tenderly wrapping her arm around her boyfriend Ethan as they posed for the cameras at the exclusive photocall.

Ethan rocked a laid-back look in a plain black dress shirt and matching pants, and he looked to be in great spirits as he hugged his beautiful partner.

The lovebirds, who went Instagram official in Australia, were accompanied by their co-stars, including Jeff Goldblum, 72, Marissa Bode, 24, Jonathan Bailey , 36 and Cynthia Erivo , 37.

The stars looked to be having a great time as they posed in front of the Sydney Opera House and Harbour Bridge.

Grande stars as Glinda the Good Witch in Jon M. Chu's highly anticipated musical fantasy film, while Slater takes on the role of a munchkin.

The singer came under fire earlier this year following the revelation that she had been having an affair with the actor behind the back of his soon-to-be-ex wife, Lilly Jay, with whom he shares a newborn son.

The pair have been incredibly private about their budding relationship ever since romance rumours emerged in July.

Ariana and Ethan met in December 2022 on the UK set of the film adaptation of the Broadway musical Wicked, in which Grande plays Glinda — the good witch — alongside Ethan as munchkin Boq.

Ariana previously dated rapper Mac Miller from 2016 to 2018, who tragically passed away due to an accidental overdose.
