'Modern Family' Star Ariel Winter Looked Totally Beautiful At Her Prom

She's all grown up.

"Modern Family" star Ariel Winter is no stranger to looking glamorous -- homegirl has been rocking a red carpet since she was just a little kid. Now, the 17-year-old actress is all grown up, and she's got the beautiful prom pics to prove it.

Ariel went full-on glam for the event, yet still maintained a subtle, simple edge. Her classic, blue lace gown perfectly complemented her curves and her long, shiny locks. Ariel was a total knockout, as you can clearly see from these Instagram posts:

Let's be real, Ariel's best accessory was her hunky boyfriend, Laurent Claude Gaudette (like is he famous, because with a name like that, he'd better be SOON). Still, like any good daughter, Ariel found time to snap an adorable pic with her dad. Aww!!

We hope that Ariel had the best time ever at prom, because even though she's been a fixture on our TV screens for years, she's clearly just a normal teenage girl at heart.
