While Khloe Kardashian is experiencing some drama in her personal life - filing for divorce on Friday from Lamar Odom - sister Kourtney is enjoying nothing but bliss in hers these days.
That's because son Mason is now four years old!
"Happy Birthday to my precious angel who has forever blessed my life," Kourtney Tweeted yesterday. "The happiness this boy brings me has no words to describe it."
The Keeping Up With the Kardashians star helped her tyke celebrate by taking him to Disneyland Tuesday and to see Disney On Ice presents Rockin' Ever After Thursday.
Dather Scott Disick also treated his son to a special day last week, taking him out for breakfast Friday morning at the Marmalade Café in Calabasas.
Sounds like a great week all around for the little guy. Happy birthday, Mason!
