Kim Kardashian Seriously Into Kris Humphries and House-Hunting in NYC

"She's moving permanently to be closer to Kris," a source exclusively tells E! News

Is Kim Kardashian taking Manhattan full-time?!

E! News has exclusively learned that the TV star is planning to move to New York City, site of the latest branch of the family boutique Dash, to be closer to her New Jersey Net, Kris Humphries.

So maybe this is serious...

"She's moving permanently to be closer to Kris," a source tells E! News.

In fact, we hear that Kardashian and Humphries, who has a place in Hoboken, N.J., were checking out a high-rise apartment in Chelsea together just this morning.

But Humphries isn't interested in a bridge-and-tunnel back-and-forth. The Nets' new Russian-billionaire owner is moving the team to Brooklyn, where they'll play at the brand-spankin'-new Barclays Center, in 2012.

"A move to Manhattan will bring him closer to Brooklyn, and he wants to live with Kim, too," the source says.
