Kendall Jenner: Holding Hands with Jaden Smith at 17th B-Day!

Kendall Jenner's 17th birthday party was probably better than yours.

The young "Keeping Up with the Kardashians" star celebrated her special day over the weekend -- with a big ice skating party in their own backyard!

Yes, Kris and Bruce Jenner actually had an ice skating rink installed behind their house for the bash ... which was attended by her sisters Kylie and Khloe, Lamar Odom, Rob Kardashian and Will Smith's 14-year-old son Jaden Smith.

Speaking of Jaden ... he and Kendall were seen holding hands for a couple's skate. He was later seen skating with Kylie as well though, so we're guessing they're just friends.
