There’s no doubt about it: Glee’s Dianna Agron (Quinn) knows how to make heads turn in her direction. The gorgeous blonde stepped out on January 9 to attend a swanky luncheon hosted by Dior Beauty and Operation smile, and we did a double take when we caught sight of her eye-popping wardrobe choice!

Dianna wore a white blazer dress to the event... and very little else. Though she’s wearing tights underneath her white hot dress, the former Glee star left other undergarments noticeably missing.

Add that to her dangerously low-cut neckline, and the result is a whole lot of exposed decolletage. Wowza.

After attending the event, Dianna took to Twitter to share a fun photo collage of she and some fellow actresses (including Meryl Streep’s daughter, Mamie Gummer) enjoying the luncheon. Yes, Di’s deeply-plunging neckline was front and center.

In just a few days, Dianna will be back on the set of Glee filming the show’s 100th episode. She hasn’t appeared on Glee for a while, and after Quinn Fabray was noticeably missing from the Cory Monteith tribute episode, many fans worried that she might be gone for good.

But never fear! Lady Di is back for March 18’s  Season 5 Episode 12: “100” and she’s even rumored to be singing one very iconic Britney Spears song with Brittany (Heather Morris) and Santana (Naya Rivera)! That, come to think of it, makes ties in with this risque, skin-baring attire perfectly. Perhaps we can expect to see something similar when she pops back up on the show?
