Competition is officially heating up in the semi-finals of our King and Queen of Young Hollywood poll. Which bright young talents will ascend to the throne? Well, the winners entirely depend on your call.

In this round, we're asking you to choose between Pia Mia and Hailee Steinfeld. They're both such strong contenders, so your decision ultimately depends on your personal preference. If you've got Ms. Mia's "Do It Again" on repeat and you love following her adventures with close pal Kylie Jenner on Instagram and Snapchat, it's pretty clear where your loyalties lie.

On the other hand, if you've practically got Pitch Perfect 2 memorized, pledge allegiance to Taylor Swift's entire "Bad Blood" squad, or simply adore Hailee's "Love Myself" ode to doin' you, she's obviously going to win your vote for the crown.

Still torn? Both stars have major projects in the works! Pia told us she's hard at work on her debut full-length, and she's logged studio time with big-name producers and artists including Benny Blanco, Ty Dolla $ign, Kid Ink and 2015's biggest comeback kid, Justin Bieber. Meanwhile, Hailee's toiling away on her own debut album and she's lined up some exciting movie roles, including Pitch Perfect 3 and Term Life with Vince Vaughn.

Weigh your options carefully, and then place your vote below. This round ends on September 7 at 5 PM ET — so get to voting! The decision now rests in your hands.

And while you're at it, be sure to vote in the other rounds of King and Queen of Young Hollywood:
