Johansson confused by Lohan slur

Scarlett Johansson has revealed that she was confused by graffiti written about her by Lindsay Lohan.

The Mean Girls actress allegedly scrawled 'Scarlett is a bloody c**t' with permanent marker on a bathroom stall in New York in 2006.

Johansson said that the incident still perplexes her two years on, telling Allure magazine: "I don't know what the motivation was. I remember it was something really vulgar - I mean shockingly so, like: 'Whoa, what, who are you?'"

Johansson added that Lohan's actions were even more confusing because the pair hardly know each other.

"I don't really know [Lohan]. I only met her, like, three times," she said.
