The battle rages on under the sun in our ongoing 2015 Beach Babe And Hunk showdown!

It's been quite the showdown so far, with Rihanna narrowly edging out "Good For You" bombshell Selena Gomez with just 50.3% (!) of the vote — proving that Rihanna reign truly just won't let up. (And judging by the music video for "Bitch Better Have My Money," she's not one to let things slide too easily. Consider yourself lucky, Selena!)

On the other hand, the same can be said for Taylor Swift and her troupe of bad ass BFFs, "Bad Blood" style. (Ironically, she too beat Selena Gomez, in video form anyway — it's been a rough one for SelGo lately, clearly.) In her own first round of PopCrush's Beach Babe of 2015, Swift successfully won over Kardashian favorite-turned-full-fledged model, Kendall Jenner, taking the crown with an overwhelming 70% of the vote. Swift means business — but we certainly knew that, too.

So here's the question: Between the two pop titans — RiRi and Tay Tay — which one will ultimately move on to rule the sand for another day? Both candidates are certainly worthy of the crown, having flaunted their hot bikini looks all summer long so far. But only one can emerge victorious. Now, it's time for you to decide.

Place your vote in the battle between Rihanna and Taylor Swift below. The poll ends on July 21 at 5 PM — so get your votes in now. Navy! Swifties! This means you! (And while you're at it, check out the full gallery of 2015's Beach Babes below.)
