Rob Kardashian has been taking a break from the limelight for some time now, and it seems as, during his hiatus, he was working on his health and weight as he recently showed off his newly svelte body on Twitter.

In celebration of his 31st birthday, the reality star took to social media to show a photo of him with his daughter, Dream, and while he's seen wearing his now uniform black tee and fitted cap, his figure appears to be much slimmer.

Take a look, below:

For years, Rob has publicly struggled with his weight, even detailing some of his hardships on his canceled reality show, Rob & Chyna, with his ex-fiancée. He explained in the past that his mental and emotional struggles hindered him from shedding the pounds and doing the work, but it appears as he's now in a more positive space to earn the results he wants.

Good for him!
