There are a lot of famous people in Hollywood who aren't actually famous, that is, they are just regular people who hung out with or dated a famous person and used that to build their own fame.
These are Hollywood's most notorious "hanger-ons."
Scott Disick is ONLY famous for dating and fathering Kourtney Kardashian's children. He once opened a restaurant in NY that closed about five months later.
Lukas Haas is a former child actor and Leonardo DiCaprio's best friend. He gets stalked by the paparazzi like a real celebrity, except all he does is party on yachts with Leo and nothing else.
Karrueche Tran is a random girl who started dating Chris Brown and now she's literally a bona fide celebrity, well sort of.
Malika Haqq was Khloe Kardashian's best-friend-turned-assistant who was fired and became just a best friend again. She's a struggling actress, but we mostly know her from Khloe's Instagram and appearances on the show. You may think she's not famous, but show us another person with nearly a million Instagram followers who isn't FAMOUS!
Melissa Forde is like Rihanna's carbon copy and her best friend. She lives the high life and it appears as if she's even on Rihanna's payroll.
Joe Jonas' now ex-girlfriend Blanda Eggenschwiler was just a graphic artist from NY before she met Joe, now she's basically a style icon on Instagram.
Cheyne Thomas was a Starbucks barista when Miley befriended him and hired him as her assistant.
Suki Waterhouse was a random struggling British model, until one day Bradley Cooper announced that she was his girlfriend. It was completely random, but whatever, now Suki is as popular as he is and booking modeling gigs left and right.
Lil Za is Justin Bieber's NUMBER 1 BFF and he calls himself a rapper, even though he has exactly ONE song out. However, he has nearly half a million Instagram followers, so whatever.
Nobody knows what Jonathan Cheban does, or who he dates, or why we care about him, but he IS best friends with Kim Kardashian and that's literally all that matters these days.
Remember CaCee Cobb? From the early days of Jessica Simpson's career when CaCee was introduced to us as Jessica's best friend/assistant? Well, CaCee is still around and still famous, all thanks to her stint as Jess's BFF.
