According to friends of the couple, who met while filming their upcoming thriller BLACK DAHLIA earlier this year (APR05), the lovebirds have decided it's time to make a commitment by sharing an abode.
A source tells Star magazine, "They're discussing moving in together in NYC. I know that they have already started looking at places to buy in SoHo and the West Village."
While Johansson's spokesperson denies the move, the friend insists that neither Hartnett or Johansson wants to be based in Los Angeles.
Unless he's working, Hartnett spends his time in Minnesota, while native New Yorker Johansson prefers living in her hometown, which she feels is more private than Los Angeles.
