It sounds like reclusive Rob Kardashian is recovering from a tough time

Rob Kardashian has posted his first selfie in a VERY long time and it’s caused quite a stir amongst his fans.

The 28-year-old star – who has shied away from the limelight in recent years but has had quite a public battle with his weight – shared a close-up snap with Instagram fans yesterday and looked noticeably slimmer.

‘Gnight,’ Rob simply captioned the black-and-white photo.

With a kind-of smile on his face, Rob appears pretty relaxed in the picture as he rests his head back and seems to have lost quite a few pounds.

The surprise shot led to an outpouring of support from fans, with one commenting on the post: ‘You look great…happy for u to feel better about yourself…be true to you..not others standards’

Another wrote: ‘You look healthy congrats baby, hard work pays off ’

It’s thought that Rob has been working out a lot with sister Khloé’s trainer Gunnar Peterson in an attempt to drop the 100lbs he gained.

A source tells E! News that he’s ‘committed’ to slimming down and he’s ‘working with a chef and doing really well’.

It’s the first time that Rob has been seen in quite a while, though he’s recently been posting things more and more frequently on social media.

The former reality star hasn’t appeared on his family’s show Keeping Up With The Kardashians since 2013 and has stayed away from the spotlight, sparking concern amongst fans.

His family have also voiced their fears for Rob in public, with Kim speaking out about his issues in an interview with Rolling Stone magazine earlier this year.

‘It’s not that mysterious, what’s happening with Rob,’ said Kim, 34. ‘He has gained weight. He feels uncomfortable being on the show, and that’s OK.

‘Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes.’

Fortunately it sounds like Rob is now in a good place and is recovering from a tough time, with mum Kris Jenner recently saying: ‘Rob is living in LA right now and he’s doing well, finding out what makes him tick and struggling with some stuff.

‘My job is to be there for him and to love him as hard as I can. Everybody goes through stuff.’
