Is Kourtney moving to New York?

Kourtney Kardashian is movin' on up...or, make that, over to Manhattan.

E! News has learned that the eldest Kardashian sister is set to pack up things in Los Angeles (including baby Mason!) this Sunday and moving to New York City.

Sources close to the sisters say  that Kourtney plans to spend at least the next two months or so in the Big Apple as she works on launching a new DASH retail clothing store in the SoHo neighborood. "She's excited for the move and to start this new venture," says the insider.

Where will she live?

E! News has learned that she will be staying, at least temporarily, at the trendy Smyth Tribeca hotel during their stay.
