Rob Kardashian has had an epic weight loss!

After Rob Kardashian reportedly made a vow to Khloe Kardashian to lose weight before the time her baby girl True Thompson was born, it looks as though he kept that promise.

Rob has been spotted by paparazzi looking slimmer than he was back in 2017.

This fan account has been posting updates.

The Daily Mail reports the photo that got fans speaking was when his sister Kim posted a photo of Rob with his daughter, Dream Kardashian, on Snapchat back in March.

Rob's been banned from Instagram following an incident with ex-fiancee Blac Chyna and isn't an avid Twitter user, so regular images of Rob are far and few between.

According to both the Daily Mail and BET, Rob Kardashian has had a rough time over the past few years, with troubles including having a messy and publicly-broken engagement with Blac Chyna, being fat shamed in the media and having his Instagram account suspended after posting revenge porn of his ex.

In an early episode of Keeping Up with the Kardashians, he admitted to having gained 100 pounds. In 2016, Kardashian publicly confirmed in an Instagram post that he weighed 248 pounds (although some speculated he was closer to 300). In an effort to turn things around, Kardashian is reported to have lost about 15 pounds.

It’s believed the reality star is keeping his weight loss under wraps for a big television deal.

Either way, it's nice to see Rob looking happier and working on his health while he's at it!
