Hailey's praise of Julien comes after he recently admitted he is a "huge fan" of her work.

He exclusively told BANG Showbiz: "It's nice to remember the past and other people who made it so special for me. I am huge fan of Hailey and all the other women I dress as well.

"She's part of a triple A-list Hollywood gang that everybody seems to be interested in - like Bella and Gigi Hadid, the Kardashian's and Hailey Baldwin. They're all friends and they want to hang out together."
