How the Beauty Looks at the MTV Movie & TV Awards Have Changed

These days, Christina Aguilera has undergone a major make-under, but 10 years ago, she was all about vintage glam with her platinum bangs, geometric cat eye, and flash of bronzer.

A pregnant Ashlee Simpson showed us all what a maternity glow looks like, with a pop-punk edge. It involved a dramatic side part and jet-black eyeliner.

Paris Hilton did as Paris Hilton does: wore her hair in a long, wavy blowout, sprinkled on some glitter pink eye shadow, and paired it all with a rosy pink gloss.

This was the year of stick-straight hair, but Lindsay Lohan went against trend with va-va-voom curls.

This could honestly be a shot from the current Ocean's 8 press tour, but instead it is visual proof that Anne Hathaway has not aged in 10 years.

This was Megan Fox's year, and she punctuated it at the awards with her go-to look: long, layered dark chocolate hair, cherry red lipstick, and a pretty serious tan.

Hot off the heels of Juno's massive success, Ellen Page opted for no-makeup makeup long before that was a real thing.

We would definitely need to ask Emma Stone for her ID back in 2008. The then-19-year-old looked fresh-faced with a deep side part, subtle bronzer, and a gold headband.

Anna Faris has kept her signature curtain bangs for most of her career, and the fringe in 2008 was in full force.

The singer and American Idol alum could have rolled up to this year's Met Gala red carpet with her ethereal hair and cherubic makeup, but instead, this is a picture of her doing that timeless boho thing really, really well a decade ago.

Mr. Big, meet Ms. Parker's bigger hair. Sarah Jessica Parker's tousled blowout almost took flight on the red carpet.

"And I am telling you, I'm not going" to stop admiring Jennifer Hudson's blunt bob, piecey bangs, and inner-eyelid highlighter.

The Hills are alive with the sound of music, as was this late-aughts glam perfection.

Lauren Conrad's thick black eyeliner and mascara may not have survived reality-show ugly-crying, but they looked damn good here.

Whitney Port's bouncy curls were worthy of their own The Hills spinoff.

Now, Kristen Stewart pushes the envelope on the red carpet, opting for edgy looks such as pearl-lined eye shadow and updos secured by approximately 400 bobby pins, but back in 2008, she was just your average vampire-loving girl-next-door from Forks, WA.

Disney's breakout star Hilary Duff let her blond hair fall down and wake (every teenager's) dreams.

Of course the early-aughts' coolest cool girl's throwback beauty look would still be chic as hell 15 years later.

Posh Spice and the man-bun pioneer David Beckham gave denim-clad Justin Timberlake and Britney Spears a run for their money with these matchy-matchy white outfits and coordinating tans.

Kate Bosworth's upswept chignon gave us a full view of her skinny brows — a major trend of yore. What we're sure she wouldn't do for a time machine that would allow her to slip some Boy Brow into her going-out clutch.

Here's a picture of Jennifer Garner wearing berry-red lipstick one year before the release of 13 Going on 30, and it's pretty sweet.

The pulled-back pompadour! The contrasting roots! The sticky gloss! Tara Reid's look had every 2000s trend wrapped in one.

This superindie singer named Beyoncé showed up to the 2003 MTV Music Awards looking like a total goddess, and then we never saw her again. Just kidding — 21-year-old Bey somehow made our college-exam-day messy ponytail look extra chic, with the help of a little red blush and a lot of thick eyeliner.

This was the year that pop culture peaked with the release of How to Lose a Guy in 10 Days. The film's star opted for a fairly timeless beachy vibe that wouldn't look out of place in 2008.

Jessica Simpson rocked two of 2003's biggest accessories: dangling earrings and face-framing hair wisps.

Yes, those are rhinestone-studded claw clips in Jennifer Lopez's (crimped) hair.

Tyra Banks may not have been smizing here, but she was wearing the most '90s blue smoky eye we've ever seen.

Friday, June 30, 1997, was Courteney Cox's day, month, and year, because girlfriend succeeded in distracting us from her see-through crochet dress with her stick-straight lob, bronze satin lipstick, and out-to-there lashes.

The exact tube of lipstick Denise Richards wore to this show is well past its expiration date, but the color is still just as hot today. Also: check out that diagonal hair part.

The OG Baywatch star showed us what beach waves are supposed to look like, topping it off with a still-trendy coral lip look.
