Kim Kardashian shares throwback snap of Rob Kardashian where he looked slimmer as he clocks 34

It was learnt that Rob Kardashian celebrated his 34th birthday on March 17. 

Meanwhile his sister, Kim Kardashian, shared a photo of him taken months ago when he was celebrating with her at her 40th birthday getaway.

Although, Rob seems to be much slimmer in the picture. 

Kim captioned the photo: "Happy Birthday Robbie! We've made so many amazing memories this last year that will fill my heart for a lifetime. I'll never forget this night a few months ago dancing the night away (yes people I danced) and our boat & whale and even shark adventures LOL The way our daughters are besties warms my heart so much! I love you more than anything and am always here for you! I am so tempted to screenshot just some of our group family chat to give people a glimpse of the crazy funny insane person you are!! I LOVE YOU @robkardashianofficial."
