The Charlotte's Web star posed with an oversized bottle of Oh, Lola! between her thighs for the campaign last year (11), sparking a furore as she was aged just 17 but looked even younger in the image.
The advert was even banned by officials at the U.K.'s Advertising Standards Authority - but Fanning is adamant she was amused by the controversy.
She tells British magazine Stella, "I thought it was hilarious. All of my friends were like, 'Yeah, you're corrupting youth with your perfume bottle and pink polka-dot dress!'... I'm constantly baffled by what people care about, when there are real problems in the world."
