Kourtney Kardashian's 3-year-old son Mason has been used to getting all the attention from the Kardashian-Jenner clan since he was born in December 2009, especially from his Aunt Kim.
But, when baby North West came along, the spotlight turned from one tiny tot to another. Kourtney revealed to People magazine that sharing the limelight with his cousin isn't easy.
"He gets a little jealous because he and Kim were so close," she explained. "He doesn't understand because he's not the big center of attention … He's like, 'Why don't you like me anymore?' because he sees her with the baby."
