The 'Perks Of Being A Wallflower' actress thinks her 'Harry Potter' co-star is a ''lovely'' person and believes that beauty is more about what's inside a person rather than outside, finding artistic qualities more attractive than looks.
When asked who the most beautiful person she has ever met is Emma, 22, replied: ''Emma Thompson springs to mind - she's such a lovely person. [Singer] Patti Smith is amazing - she seems really youthful but with the wisdom of someone who has been on the earth for a thousand years.
''And I really respect ['Lost In Translation' director] Sofia Coppola and her artistic sensibilities.''
Emma, who has made the '100 Sexiest Women' list by FHM magazine every year since 2007 and fronted campaigns for brands such as Burberry and Lancome, admits that even she sometimes has ''bad days'', but always reminds herself how lucky she is to be ''healthy'' instead of worrying about her looks.
She explained to Marie Claire magazine: ''I cope [with bad days] by putting them into perspective. If I'm having a bad day I just remind myself to be thankful that my body works and that I'm healthy, and I try to focus on things that are going right about my day.''
