After a three year absence from hit show Keeping Up With the Kardashians, it looks like brother Rob is set to rejoin his sisters in the limelight. Rob, who quit the show back in 2012 amongst rumours of depression and weight gain, has sparked speculation of his return when he started actively posting on social media again. Now sister Kim has hinted that we might get a glimpse of the 28-year old, as she documented a hike during her pregnancy where she tagged her younger brother in the struggle:

Rise & Grind! Workout time!!!!! With @robkardashian ❤️??

Fans of the show now believe the hike could be Rob’s gradual reintroduction to the show, with many believing Kim could be helping ease her brother back into their hectic filming schedule. The news comes in the same week Rob posted two photos to his Instagram account, marking a noticeably slender facial selfie and toned arms.

The photos marked a slow reintroduction to his former lifestyle, with Rob sharing a family snap of brother-in-law Kanye kissing daughter North in early August. While he had been keeping a distance from the publicity of the KUWTK TV show, his return to social media could point at the young Kardashian’s hopes to rejoin his sisters. Speaking to US Weekly about an upcoming return, a family friend said: "He has a $2 million-a-year contract. He realised he couldn't give up this huge opportunity."
