Now that the nominations for the 2013 Teen Choice Awards have been announced, all of you pop lovers get to vote on your favorite singers in a variety of categories. The race for Choice Female Artist of 2013 is sure to be one of the most heated categories in the fan-voted awards, as Selena Gomez, Demi Lovato, Pink, Rihanna and Taylor Swift are all competing for the title. 

So, out of these five females, who do you think deserves the title of 2013's Teen Choice Female Artist the most? You can read up on each nominee below, and you can vote once per hour until the poll closes on Sunday, August 11, at 7:59 PM EST. The 2013 Teen Choice Awards will air on Fox immediately after, starting at 8PM ET.

Selena Gomez: When she isn't dating and breaking up with on-again, off-again boyfriend Justin Bieber, Selena Gomez has been keeping busy performing new hit songs like 'Come & Get It' and prepping for the release of her first solo record (minus the Scene) 'Stars Dance.' She also has an international tour coming up, with her first date scheduled for Aug. 14 in Vancouver. Additionally, Gomez hasn't forgotten her acting roots, starring in the 2013 Harmony Korrine flick 'Spring Breakers.'

Demi Lovato:  Fresh off her first season as an 'X Factor' judge, and prepping for the next season of the reality singing competition in the meantime, Demi Lovato has been doing big things in both music and television. When she wasn't coaching songbirds on TV this past year, Lovato was hitting the studio hard, recording her latest studio LP 'Demi,' which features her smash single 'Heart Attack' as well as a bevy of other infectious tunes that show off her insane vocal abilities.

Pink: 'The Truth About Love,' released in Sept. 2012, has been one of Pink's greatest albums to date, and that's saying a lot because Ms. Moore has been a pop mainstay since she broke onto the scene in 2000 with 'Can't Take Me Home.' Since the album dropped, Pink has been churning out hit single after hit single ('Blow Me (One Last Kiss),' 'Try,' 'Just Give Me a Reason'). And while she isn't spending time with her family, Pink has been giving fans her all on stage during her string of tour dates, which will remain in full swing throughout Dec. 2013.

Rihanna: While the details of Rihanna's personal life are a bit dramatic, there is no denying that her immense talent and crazy work ethic exceeds the drama. The latter half of 2012 saw the release of her seventh studio album 'Unapologetic,' and her Diamonds world tour with ASAP Rocky has been selling out all over the place (with dates scheduled internationally up until mid Nov. 2013). RiRi has also had some major hits on the radio this year, like the emotional ballad 'Stay' and the Sia-penned smash 'Diamonds.'

Taylor Swift: And closing out the 2013 Teen Choice Award nominees is Taylor Swift, who is currently entrenched in the biggest year of her career yet. Her latest LP 'Red' has moved her from country-pop territory into full-blown pop superstardom, and songs like 'We Are Never Ever Getting Back Together' and 'I Knew You Were Trouble' landed in the top spots on the Billboard Hot 100 (the former hit No. 1, while the latter peaked at No. 2). Her accompanying tour with Ed Sheeran has also been one of her biggest and baddest (in a good way) stage productions thus far, which is probably why it sold out in .2 seconds.
