The Keeping Up With The Kardashians star held her olive green trench coat closed so photographers couldn't get a glimpse of her midriff.
She did, however, show off plenty of cleavage!
Kim, 34, announced her second pregnancy at the end of May and then used Father's Day weekend to confirm she and husband Kanye West are expecting a baby boy.
They are already parents to daughter North, two.
Ahead of jetting out of Los Angeles on Monday (22 June), the starlet had spent Father's Day with stepparent Caitlyn Jenner, who posted a picture to Twitter showing several members of the Kardashian Jenner clan off-roading in the desert.
Kim also paid tribute to her father, the late lawyer Robert Kardashian, by sharing a throwback image of her with him alongside the caption: "My first day of school, my daddy was there in his Fila track suit."
