The oldest Kardashian sister bared her baby bump when she posed nude for DuJour magazine. “It’s a wonderful thing to be able to show my children these photographs one day and say, ‘This was you inside,'" she told the magazine. “I’m at my best when I’m pregnant.”
While Kourtney was in the hospital, her son Mason celebrated his 5th birthday with his aunt Kim Kardashian, sister and cousin North West at Disney on Ice. Next year he’ll be celebrating his birthday with Reign!
