Scarlett Johansson and Ryan Reynolds’ relationship is reportedly on the rocks, reports.

The 23-year-old star — who has been dating the Definitely, Maybe actor for a year — feels she is too young to settle down and wants to concentrate on her career.

A source said: “Scarlett and Ryan have hit a rough patch after he dared to broach the subject of marriage and kids. Scarlett is younger and has no desire for a husband or family just yet.”

It was recently reported Scarlett had moved into Ryan’s Los Angeles home even though her mother didn’t approve. However, friends say she is just using his home as a base while she travels the world working on movies.
