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 kicks off today, with two very different pop princesses in the running for the ultimate social crown.

First up is Selena Gomez, the former Disney darling with a "Fetish" for gorgeous Instagram photos and who is currently the most followed celebrity with over 123 million followers. She's proven her royal status, but does she have what it takes to seize the ultimate crown?

Up against Selena is crystal-voiced K-pop princess Taeyeon, who is currently one of South Korea's most followed idols on Instagram, where she enchants with stunning selfies, performance photos and the occasional Girls' Generation throwbacks. Will she rule as 2017's Social Media Queen?

The battle starts now: Place your vote between Selena Gomez and Taeyeon for 2017's Queen of Social Media! This round ends on Friday, July 28 at midnight.
