If ever there was a forum for mindless self promotion it's Instagram. Celebrities and wanna-be celebrities have no shame when it comes to posting outrageously self-aggrandising shots - and they're laying themselves open to satire.Last year's @socialitybarbie account saw the Instagram-vacuous parodied for their pseudo-soulfulness. But Barbie isn't the only one making the most of pop culture moments.Also in on the game is Australian comic Celeste Barber, who's turned her Instagram feed into a funny tribute (or mockery) to celebrity Instagrams of unprecedented silliness. Kendall Jenner's hair hearts and Kim Kardashian's metallic bodysuit are all fair game."Some celebrities on Instagram seem to think we, non-rich, non-privileged people are idiots and believe that what they are posting is real," Barber told BuzzFeed Life. "I wanted to try to show how ridiculous it would be for a 'normal' person to recreate some of these photos." See @celestebarber...
