Does your fave have what it takes to rule over the kingdom of social media? PopCrush's King & Queen of Social Media Contest is a month-long competition to determine 2017's social media pop royalty.

This year’s King & Queen of Social Media competition speeds into Round 2, with two global pop stars battling it out for the ultimate social crown.

First up is Justin Bieber, the Canadian pop star whose on-again, off-again relationship with social media has nonetheless garnered him nearly 90 million loyal followers on Instagram alone. Is Justin the Purposeful king social media deserves in 2017?

With over 10 million followers, EXO star Sehun battles the Biebs for the throne. Known (currently) for his vibrant tangerine hair and equally bright personality, the South Korean rapper and singer puts up a good fight, but does he have what it takes to seize the crown?

The battle continues: Place your vote between Justin Bieber and Sehun for 2017's King of Social Media! This round ends on Friday, August 4 at noon EST.
