Kim Kardashian has showed that she was serious in romancing footballer Miles Austin. The Hollywood Life reported that the ex-girlfriend of Reggie Bush has taken the 26-year-old to meet the rest of her Kardashian family in New York City as they celebrated Khloe Kardashian's birthday on Saturday night, July 3.

In the gathering attended by mother Kris Jenner, sister Kourtney Kardashian, Kendall Jenner and Kylie Jenner, and Khloe's Lamar Odom, Kim and the Dallas Cowboys wide receiver enjoyed a yacht ride in New York harbor. The next morning on July 4, the twosome were spotted shopping together at a local shop Rite Aid before heading to Chelsea Piers to watch Macy's the 4th of July Fireworks Spectacular.

29-year-old Kim has been seen stepping out together with her NFL boyfriend few times before. On June 6, they was spotted cuddling and drinking margaritas at Casa Vega in Sherman Oaks, Los Angeles. Days later on Wednesday night, June 30, they were caught on camera for the first time when stepping out to New York City's STK restaurant to celebrate Miles' 26th birthday.
