It's been a rough week for Khloe Kardashian, who filed for divorce from husband Lamar Odom on December 13 after months of speculation about their marital trouble. Now, it looks like she is turning to a surprising person for support.

Khloe herself has had a lot on her mind over the past few days, but she apparently isn't too busy to wish nephew Mason a happy birthday. Mason — whose parents are Khloe's sister Kourtney Kardashian and Scott Disick — turned four years old on December 14.

Khloe took to Instagram on Mason's big day to post a collage of photos of herself with the cutie. "My happiness is this little man!" she captions the photos. "Happy birthday, Mase!!" So sweet!

Khloe also posted a photo of her feet entwined with Mason's feet as the two relax together in matching star-patterned pants. "⭐️⭐️⭐️⭐️⭐️ Mase and KoKo," she captions that one. Hey, Khloe  any chance you can get us a pair of star pants so we can all match? Thanks a bunch!

It's great that Khloe has her family around to help keep her mind off the split from Lamar. Lamar reportedly "expected" the divorce, and sources say Khloe herself is now dating baseball star Matt Kemp

Are you glad Khloe and Lamar are finally done? And do you think she and Matt are a good match?
