There he is -- the new Mr. Kim Kardashian!

Kim Kardashian stepped out at NYC's STK restaurant with her new boyfriend, Dallas Cowboys wide receiver Miles Austin. It's the first time the new couple have been snapped together.

The occasion: Miles' 26th birthday. "Kim threw Miles a birthday party," a source tells UsMagazine.com. And Austin's new gal wasn't the only Kardashian in attendance, either. Kim's sister Kourtney Kardashian, 31, also showed up with boyfriend Scott Disick.

Kim, 29, and Austin were first spotted together on June 6 drinking margaritas at Casa Vega in L.A's Sherman Oaks, Calif.

"They are dating, but she doesn't want to rush anything," a Kardashian insider told Us of the new pairing. The reality star broke up with Reggie Bush -- another football pro -- earlier this year.

"Kim wants to date someone who gets her busy lifestyle," adds a friend.
