Rob Kardashian all smiles in rare photo of the night with his sisters

It was worth the wait.

After Facebook, Instagram and WhatsApp suffered day-long outages on Monday, Kim Kardashian relaunched Instagram with a treat: a rare photo of Rob Kardashian, who was smiling from ear to ear.

The 40-year-old Skims founder shared two photos – one of Kourtney Kardashian and her boyfriend Travis Barker and one of Khloé Kardashian smiling next to Rob – and captioned them, “Dinner with my favorite couples.”

The foursome photos were apparently taken during Kylie Jenner’s birthday celebration in August.

Many of the former Keeping Up With the Kardashians star took to the comments to joke about the caption “couples”, with hairstylist Jen Atkin writing, “I knew you were dating !! @khloekardashian the called.

Even Khloé, 37, had fun by joking, “FOEVA @robkardashianofficial”.

“Why did you say favorite couples and there’s a pic of rob and khloe😭😭,” commented one fan, who clearly missed the joke.

Others focused on the fact that the reclusive Halfway Dead founder, 35, was pictured on social media and took a moment to salute how happy he looked.

“Rob looks great! I love to see it 😊 ”commented one subscriber.

“Rob looks so good!” writes another.

“Wow Rob looks sexy af 😍,” commented another.

Arthur George founder was last seen on Instagram in June, when Khloé posted a selfie with Kylie Jenner and her younger brother at her birthday party.

Khloé brought up Rob’s reclusive lifestyle at the Keeping Up With The Kardashians reunion, which he did not attend, and said he took a step back from the cameras because of the way whose women treated him.

“It’s not so much about physical appearance,” she said, referring to Rob’s past struggles with his weight. “It’s a lot how he felt inside about some of the women in his life and how they treated him or how he thought they could have used him to reach certain areas or levels. “

Khloé told reunion host Andy Cohen that Rob’s failed romances over the years – not to name Blac Chyna – had “really affected” his self-esteem, adding: “My brother is a lover and has a heart. and the most incredible personality. “
