Rob Kardashian is officially back on Instagram after a brief hiatus. In July the occasional “Keeping Up With the Kardashians” star wiped his account of all photos, a majority of which featured fiancée Blac Chyna.

On Thursday Rob, 29, returned to the photo-sharing app for a noble cause — to celebrate little sister Kendall Jenner and her most recent modeling accomplishment. The Arthur George sock designer shared a photo of Kendall’s Vogue cover for the publication’s highly anticipated September issue. In his caption Rob raved about his “baby Sis,” acknowledging just how big an honor she had received. The photo garnered nearly 800 comments and more than 120,000 likes from fans.

Many believed Rob’s silence on Instagram was a sign his relationship with Blac Chyna, 28, was on the rocks. Just two months after the duo announced that a reality show surrounding their relationship had been greenlit by E!, TMZ reported that the show was in trouble. Rob was said to have been skipping filming sessions. Blac Chyna continued to attend, but producers feared they would not have enough usable footage of the couple for the show. According to the publication, Rob feared appearing on “Rob & Chyna” would tear he and his fiancée apart, claiming that “KUWTK” damaged relationships in his family. It was later reported, however, that filming for the reality series — which will follow the couple up until the birth of their first child together — would continue.

Rob’s Instagram cleanse also lead to confusion about whether he and Blac Chyna would walk down the aisle. It was reported that the reality star, who unfollowed Tyga’s ex-fiancée on the social media site in addition to removing all photos of her, has ended his engagement. Days later, much to the delight of fans, Us Weekly reported that Rob and Blac Chyna were back together following an explosive falling out. On July 26, the expectant mother of one was seen posing with her engagement ring on in Snapchat videos.
