Dianna Agron Nip-Slip Wardrobe Malfunction PHOTOS: 'Glee' Beauty Suffers Epic Braless Boob Flash, Flirts With Josh Hutcherson?

Oops! "Glee" starlet Dianna Agron suffered a MAJOR wardrobe malfunction while attending Alexander McQueen's "Savage Beauty" fashion gala in London on Thursday evening (March 12). Wearing a bra (or at least nipple pasties) might come in handy next time...

The 28-year-old blonde bombshell looked absolutely stunning in a classy black ball gown:

But the sultry, off-shoulder dress revealed a bit too much skin as Agron was promptly escorted into the private exhibit hosted at England's prestigious Victoria & Albert Museum:

Nip-slip alert! Agron's bare side boob is put on full display while the "I Am Number Four" actress appears totally unware of the rather embarrassing fashion faux pas.

Agron continues ignoring the viral boob flash, and has yet to respond on Twitter.

The young fashionista posed topless for a racy photo shoot with Brian Bowen Smith back in October, so flaunting some sexy skin is really no biggie:

@DiannaAgron: "Seeing first images from our shoot @brianbowensmith @GeorgieEisdell @CWoodHair."

broke things off with boyfriend Thomas Cocquerel and rumors suggest that she was recently spotted "flirting" with "Hunger Games" heartthrob, Josh Hutcherson. Both stars attended a pre-Oscars party on February 22nd, and an alleged Page Six insider reveals that they were "at each other's sides all night... They were even on the dance floor together. They looked like a 'new couple' - still flirting." Cute?

Perhaps a fresh Hollywood blossoming romance for summer? Wonder if Agron's ta-tas managed to capture the 22-year-old actor's attention...

In more exciting news for Agron, "The Family" beauty is currently working on a slew of upcoming film projects including "Tumbledown," "A Conspiracy on Jekyll Island," "Bare," and "Pretenders." Stay tuned.
