London: Legendary director Woody Allen is concerned that Scarlett Johansson could ruin her career if she parties too much.

Thesun.co.uk reports quoted him as saying: "Johansson is so beautiful and so sexy and so gifted... she can do anything. But she has to make the right choices of films and she's got to not go the Page Six party route.

"I don't want to read about her in the paper with this boyfriend or that boyfriend, or in rehab or taking pills. I don't think she's always made great choices. She has to take her acting seriously... the way someone like Meryl Streep did it."

He has worked with Johansson in movies like "Scoop" and "Match Point".
