Blast from the past!
On Saturday, the entire Kardashian family were reminiscing on their personal websites over Rob Kardashian's 25th birthday.
Taken when she was 31-years-old, Jenner poses topless wearing just white underwear while showing off her massive baby bump.
"Happy 25th birthday to my wonderful, handsome son, Rob!! Rob, you are the best son a mother could ask for and you make me proud every day. I love you so much!!" Jenner, now 56, wrote on her blog.
Jenner and Kim Kardashian celebrated with Rob at his swanky birthday bash that took place at Las Vegas hotspot 1Oak on Friday.
While Jenner wore a red-hot form-fitting dress, Kim flaunted her famous curves in a white mini dress decorated with patches of silver sequins.
