Justin Bieber's New Hairstyle: The Trump?

Teen pop phenom showed off his throwback new 'do while making the rounds at the Consumer Electronics Show this week—but there's something strangely familiar about it...

You know what they say about the couple that changes hairstyles together…

The new year is as good a time for reinvention as any, and fresh off the transformative 'do debuts of Demi Lovato, Katy Perry, Robert Pattinson and even girlfriend Selena Gomez, Justin Bieber has joined in on the hair-changing fun, showing off his new look while making the rounds at the Consumer Electronics Show in Vegas this week.

Turns out, what's old is new again. But it's not just Bieber's trademark and newly-resurrected swoop that looks so familiar.

So where have we seen this look before?

Oh, right: on top of Donald Trump's head. (You've gotta admit, the resemblance is uncanny.)

The swoop's resurgence—shown off while Bieber helped unveil the TOSY mROBO Robot at the convention—harkens back to the early days of Bieber-mania and marks a departure from his more mature, closely-shorn look of late.

Meanwhile, Bieber wasn't the only star to debut his new look at CES—heck, he wasn't even the only star named Justin to do so.

The newly engaged Justin Timberlake also showed off a more hirsute look, sporting a beard when he made the rounds.

So, which Justin hairstyle do you prefer? Old or new?
