Kim Kardashian & Miles Austin: Dinner Date

Kim Kardashian steps out with her new rumored boyfriend, Dallas Cowboys wide receiver Miles Austin, at STK restaurant in New York City on Wednesday night (June 30).

Kim, 29, celebrated Miles’ 26th birthday at STK before heading over to SL Lounge for the after-party.

The group was accompanied by his sister Jen and her sister Kourtney (and her man Scott Disick). Looks like both parties are already mixing families!

Last month, the couple cozied up to each other at Casa Vega in L.A.’s Sherman Oaks on June 6.
