Sydney Sweeney Sizzles in Luxe Denim for Bold New Fashion Campaign

The heartthrob high-fashion muse star Sydney Sweeney ditches loungewear for stylish, striking denim as she models in a new sizzling fashion campaign.

Speaking with PEOPLE, Sweeney quickly reminded fans of her love for sweatpants as she said that she "wouldn't be caught dead" wearing jeans on a plane, unless American Eagle sponsors those jeans.

"I am a sweats girl," she said. "But yesterday I wore a pair of American Eagle jeans on a plane, and I was like, 'Oh, this is great. They're so comfy.'"

Hence, when she was offered to be the face of the brand’s latest denim campaign, she was thrilled to do so.

"I was freaking out because I was like, 'This is perfect,' and I was so excited," she confessed, adding that she has been a true fan of the brand’s jeans since forever.

Sweeney expressed the moment she received the offer: "When they were like, 'We want it to be a denim campaign,' I was through the roof. I was like, 'This is it. This is Syd. I will be able to bring this to life. You have no idea.'"

The jeans collection has both baggy, light-washed jeans as well as bold blue jeans and jackets.

"They're the comfiest jeans I've ever worn. I don't know why anyone wears anything else," the two-time Primetime Emmy-nominated actor said.
