2015 saw no shortage of high-profile celebrity feuds, and in this year's Fan Choice Awards we're giving readers a chance to decide which is the shadiest of all.

In a blessedly unscripted moment, Nicki Minaj took aim at Miley Cyrus during the 2015 MTV Video Music Awards for unsavory comments she made about Minaj in a New York Times profile. Lending the show its biggest buzz-worthy moment, Minaj addressed the VMAs host and asked, “Miley, what’s good?" Cyrus, clearly flustered, made a half-hearted attempt to throw the Times journalist under the bus when she said, “Hey, we’re all in this industry, we all do interviews and we all know how they manipulate s–t." Sure.

But that moment may never have happened had pop music’s golden child, Taylor Swift, not engaged in a light Twitter spat with Minaj, too. In an attempt to prove a self-proclaimed brand of feminism that ultimately lacked intersectionality, Swift made Minaj’s VMAs tweets all about her, writing, “I’ve done nothing but love & support you. It’s unlike you to pit women against each other. Maybe one of the men took your slot..” Minaj responded, Katy Perry got involved, think pieces were written and a media backlash against Swift brewed— prompting the "Style" singer to publicly apologize to Minaj.

Zayn Malik, meanwhile, managed to keep his name in the press following his abrupt departure from One Direction by burning bridges via Twitter. He not only shocked fans by calling out music producer and former best bud Naughty Boy with the posting of a single Tweet, but he trampled any notion of lingering friendliness between his ex-bandmates when he asked Louis Tomlinson to “remember when you had a life and stopped making bitchy comments about mine?” Months later he called it quits with former fiancee Perrie Edwards, and then further shaded her band Little Mix when he RTd a post supporting Fifth Harmony over Little Mix. It's been a rough year for Zayn fans.

Rebel Wilson took launch at the most obvious celeb target when she said she'd turned down the chance to work alongside the Kardashians: "…it’s just that everything they stand for is against everything I stand for...It’s not that you hate any of them individually…they’re not famous for talent. I worked really hard to get where I’ve gotten to." She later apologized, though she also said it was in order to get the reality stars' PR rep off of her back.

Justin Bieber proved he doesn’t pay attention to his competitors after admitting he didn't know who Shawn Mendes was during a radio interview — despite Mendes’ chart-topping hit “Stitches.”

Then again, Bieber also claims to have no clue who his recent critic Bette Midler is, saying in a Billboard profile, “This Britt Meddler…I don’t even know who that is, honestly.”

Frankie Grande had a few things to say about Selena Gomez’s hit “Good For You,” posting a lengthy diatribe on Instagram that urges fans to "Look good for YOURSELF" and "attract someone who thinks self-esteem is hot, not someone who likes to be catered and pandered to. Don’t show them how proud you are to be theirs, show them how proud you are to be YOURS."

2015 also saw Demi Lovato call out both Pink and Kathy Griffin in an attempt to defend her mediocre VMAs performance, while Austin Mahone subtly shaded ex-girlfriend Camila Cabello when talking about his then-girlfriend Becky G. He said in an interview that his relationship with Becky was his first, and that he'd "never had, like, a real relationship before, so it’s pretty crazy." Ouch.

But Britney Spears may have been the true queen of subtlety this year, when she subtweeted co-collaborator Iggy Azalea following a Twitter outburst from the Australian rapper in which she tried to explain away poor sales of their single "Pretty Girls."

Those are the options, and the rest is up to you. Be sure to cast your vote below before the poll ends on December 15 at 5 PM ET!
