Rob Kardashian has referenced his weight gain for the first time since his weight ballooned.
The star, whose family have been very vocal about his struggles, has stayed out of the spotlight for almost two years.
But it looks like Rob is steadily getting his life back on track and is now finally able to poke fun at himself.
The 28-year-old, who was thought to have gained 100lbs, shared a picture of himself looking slim as he sips on a massive milkshake.
He wrote next to the snap which was taken in 2011: “Started right here with these milkshakes hahahah #throwback Thursday.”
It comes after his personal trainer said he has been hitting the gym a lot recently.
Trainer to the stars Gunnar Peterson, who also works with Rob’s sister Khloe, told People magazine: “Rob is always in!”
He added: “He’s slammed schedule-wise and still makes this work.”
Rob’s sister Kim Kardashian has also made no secret of the fact she’s been helping her little brother to get back into shape as they patch up their rocky relationship.
Earlier this week Kim took to Twitter to write: “Rise & Grind! Workout time!!!! With @robkardashian.”
And last week she shared: “Just went on the hardest hike ever today with @robkardashian.”
Meanwhile, reclusive Rob also recently revealed he had also bumped into sister Kylie Jenner and her boyfriend Tyga while exercising.
Rob posted a picture of the pair to his Instagram on Monday, writing: “Spotted these fools on the morning workout.”
