Get ready for those terrible twos!
Kourtney Kardashian and Scott Disick's adorable son Mason turns 2 years old on Wednesday. Kourtney, who is pregnant with her second child, gushed about Mason on Twitter.
"Happy birthday to the love of my life," the 32-year-old wrote. "My precious little angel. It is my joy to see you grow every single day."
"Happy Birthday, Mason," Aunt Khloe, 27, tweeted. "You are one of the greatest things to happen to our family! I love you like you will never understand!"
So how will little Mase take to having a little brother or sister? "I think he is going to be in for the surprise of his life," Kris told Us Weekly earlier this month. "He is going to have to share the attention!"
When Kourtney announced her pregnancy, Aunt Kim told Us Mason was "the best baby ever" and added, "I can't wait to be an aunt again!"
