New couple alert? Jack Quaid held hands with his The Boys co-star Claudia Doumit as they went sight-seeing around Sydney

Jack, 31, kept it casual for the outing, wearing white sneakers, jeans and a khaki knitted sweater layered with a navy coat.

Meanwhile, Claudia also rocked jeans and sneakers, but kept herself warm in a grey coat, cropped jumper and black beanie.

The 31-year-old Sydney-born star accessorised her look with a black crossbody bag and pair of sunglasses.

Jack, who’s the son of Hollywood stars Dennis Quaid and Meg Ryan, arrived in Sydney from the US on Monday with his The Boys co-stars Chase Crawford and Jessie Usher.

The trio, along with their female co-stars Claudia and Karen Fukuhara, attended the Sydney VIP premiere of Episode 4 of the show on Tuesday.

Claudia, for her part, looked sophisticated in a cream suit jacket and trousers along with bold gold earrings and chain gold necklace.

Jack previously dated actress Lizzy McGroder, who he was first linked to in July 2016.
