Actress Scarlett Johansson first grew close to director Woody Allen after bonding over their shared phobia of falling ill.
Allen directed the beauty in Match Point and Scoop, and then again in 2008 film Vicky Cristina Barcelona.
Johansson tells Vogue magazine the secret to their long-lasting friendship lies in the fact they're both hypochondriacs, who constantly check each other for various medical ailments.
"He shakes a lot of hands. I'll squirt some (anti-bacterial gel) in my hand and then squirt in his," she says.
"The only reason why Woody and I are still friends is because I've diagnosed all kinds of his skin tags, lesions, ailments. I've prescribed things for Woody that he's then asked his doctor to prescribe for him."
