Rob still lives at Khloé’s… but here’s why he skipped THAT family photo

It's the Thanksgiving family picture that's grown legs.

Kylie Jenner and Kim Kardashian both shared a snap of their "blended family" after gathering at their sister Khloé's house for dinner last week – but it certainly raised a few questions.

Earlier this week we revealed exactly who that not-so-unknown stranger was to the very left of the photo, but one question remained – where on earth was Rob?

Once a regular feature in Kardashian-Jenner photos – and a familiar face on their reality show – Rob has been virtually unseen for the last year.

Despite living in Khloé's Calabasas mansion, the 28-year-old, who dated singer Rita Ora back in 2012, was notably absent when his older sister hosted Thanksgiving for the family.

Now though, the family momager Kris Jenner has spoken out, saying Rob was indeed present for dinner, but he declined to be in the family snap.

"He lives with Khloe, so he was around and then went over to a buddy's house," she explained on radio station Sirius XM yesterday.

Over the last 18 months, there have been repeated worries for Rob's health, with Kris saying earlier this year that she feared her soon could "die" if he didn't agree to make some "drastic" changes to his life.

Speaking yesterday, the famous mum admitted her son was trying hard to change his ways.

'He's doing alright, he's doing his best," she said. 

As for Caitlyn, who made a rare appearance along with Kris' and the former couple's children, it turns out she was not present for the full day.

"Caitlyn kind of did a 'drive by.' Came by, spent some time, then went on to do the family rounds, because everyone is scattered out all over the place."

Hopefully that's ALL the questions answered… at least until the family Christmas card comes out.
