Serena Williams Spotted Chilling With Kim Kardashian (Photos)

Serena Williams was spotted by paparazzi as she stepped out on a dinner date with Kim Kardashian few hours away from her epic tennis battle in the quarterfinals at the U.S. Open with her sister Venus.. 

Serena and Kim showed up in an SUV at Carbone in New York for some Italian food. 

Serena and Venus have faced off 27 times over the years ...and Venus has won 11 times -- so, it's not going to be a walk in the park for Serena.
