The 49-year-old supermodel insists the human rights lawyer - who is married to actor George Clooney - doesn't need any style tips from her.
She told People magazine: ''Amal is an incredibly fashionable person so she doesn't need my advice ... I guess we talk about fashion in a way, but it's not like we pore over magazines together. It's more like, she'll ask me, 'Who is your favourite photographer.' She's interested in my life, just like I'm interested in her life.
''I think one of the things I love about Amal is that she's not only interesting - she's very interesting to talk to - but she's also interested in your world as well. She can talk to my kids about their thing, or she'll talk to me about my book or my business.''
Meanwhile, the 'Monuments Men' star previously admitted he feels like an ''idiot'' when he talks to Amal.
He explained: ''Often times I feel like an idiot talking to my own wife. It's never good.''
And George - who recently celebrated his first anniversary with Amal - also revealed he failed to buy her a gift to celebrate the occasion.
He shared: ''Sometimes you just go to dinner, you know? This is the paper anniversary, you don't want to go too crazy on the first. You've got a lot more to do.''
