Rob Kardashian has shown off his stunning weight loss as he poses shirtless by the pool, in the Californian sunshine.

The 33-year-old Keeping Up With The Kardashians star has grown in confidence in posting photos of himself in recent weeks, after embarking on a diet and health kick that have returned impressive results.

The reality star had been taking a back step from the spotlight, especially as sisters Kim, Khloe and Kourtney continued to be so prolific on social media.

Since trimming down, Rob has looked to bring his fans some selfies to show how good he is looking and his followers are loving the transformation.
