WWW- SCARLETT JOHANSSON is “sexually overwhelming” according to veteran film maker Woody Allen.

The director reckons he finds it impossible to concentrate when he’s around the 21-year-old starlet.

He admitted: “It’s very hard to be extra witty around a sexually overwhelming, beautiful young woman who is wittier than you are. Anytime I say anything amusing, Scarlett tops me.”

The pair hit it off when Scarlett starred in Allen’s London-based film Match Point last year.

The beauty described the banter between the pair as an updated version of Billy Wilder and Marilyn Monroe’s, in which Allen plays a cranky wise-cracking man with Johansson able to give as good as she gets.

Scarlett claimed she was shocked to find that Woody is “actually very sweet and thoughtful and romantic, in his own strange way”.
