It's Taylor Swift vs. Rihanna in Round 1 of Hottest Star of 2014! While both singers are some of the biggest names in the business, only one lady of pop can move onto Round 2, becoming that much closer to winning the title of Hottest Star of 2014. Who has your vote?

Taylor Swift worked unbelievably hard this year, concluding her Red Tour in Singapore after a whopping 15-month stint on the road. Somehow, in between tour dates and creating the best-ever Drake-themed needlepoint for her BFF Ed Sheeran, she has found time to pen her highly anticipated upcoming album, which she has said is "already my favorite thing that I've ever created." Swifties, if that doesn't get you excited, we don't know what will!

2014 is the year that Rihanna became a fashion icon (literally, she just won the Fashion Icon Award at the CFDAs), and the Barbadian singer is never one to shy away from starting a fashion trend, whether it's rocking a daring green lip or donning a jaw-droopingly sheer gown. Of course, Rihanna is still hot on the music front, winning Artist of the Year at the 2014 iHeartRadio Music Awards and seeing 'The Monster' (her crazy catchy collab with Eminem) scoring another No. 1 hit. She and Em will hit the road this summer, embarking on the Monster Tour, selling out numerous venues, including the iconic Met Life Stadium in NYC. Rihanna is on fire!
