Taking the after party to Blind Dragon in West Hollywood, the sisters, who dressed as fairies, smiled seductively at the camera as they sat beside their much-slimmer brother in a booth. Rob wasn't looking at the photographer. Instead, he is seen looking in the distance showcasing his thin side profile. Wearing his signature blue Los Angeles Dodger baseball cap, Rob Kardashian covered up in a bright orange sweatshirt. "5am birthday adventures with my two fav people," Kylie captioned the sweet shot with her siblings. So many fans filled her comments with words of support for Rob. "Rob looks so good," one person replied on the photo. "ROB LOOKS HOT," wrote another.

Kendall made sure to repost the photo too, but instead of dedicating a post, she shared it on her Instagram story. "This moment makes me the happiest," the model wrote. As The Blast reported, Halloween night at Kendall's party was the first time we've seen Rob in ages. He later shared a snap with his mom all dressed up at the party. Although he was in character as a Troll doll, it was easy to spot his weight loss. Posting the photo to his own Instagram account, Rob wrote, "Halloween 2019."

He hasn't posted a photo of himself in a long time and his comments immediately flooded with shocked fan reactions. "ROB IS BACK," several wrote. Others showered him with compliments like "You look so good!" and "OMG Rob good for you!" That wasn't the only Halloween snap he shared with fans either. He also posted a sweet pic of his daughter, Dream, who he shares with his ex, Blac Chyna. Showing her as a Troll too, he captioned it, "Poppy Troll dressed up with Papa Troll for #Halloween."

Rob also gained attention when he was seen getting cozy with Kylie's best friend, Stassie Karanikolaou. He was photographed with his hands on the social media influencer as the two left Kendall's birthday to head to the after party. Rob Kardashian resurfacing wasn't the only highlight from that night. Kendall Jenner's party was filled with her celebrity friends who brought it with their Halloween costumes. Some definitely worth mentioning include Gigi Hadid, who dressed as Stanley Ipkiss from "The Mask," country singing sensation Kacey Musgraves dressed as a Dallas Cowboys Cheerleader, and Emily Ratajkowski channeled "Sopranos" character Carmela Soprano in her underwear.

The KarJenners went all out too. While Kylie and Kendall wowed as fairies, Khloé dressed as Cruella de Vil, Kourtney was Dolly Parton, and Kim faced backlash for editing her daughter into their Flintstone family photo.
