The 27-year-old new 'Britain & Ireland's Next Top Model' judge is a huge fan of the popstar but despairs of her style choices, reported Contactmusic.
"I love her so much and want her to succeed and she has so much potential. Her style choices, as well as her hair and make-up, could do with a little sophistication," she said.
However, there are some celebrities whose style Port admires, notably famous British faces such as Cheryl Cole and the Duchess of Cambridge.
"Cheryl Cole's great. I love how she defies fashion boundaries. And Kate Middleton is doing an amazing job staying appropriate with fashion in the role that she's in with all eyes on her. I especially love the grittiness of east London fashion - girls like Alexa Chung and Rosie Huntington-Whiteley have influenced a lot of my new Whitney Eve collection," she added.
