Jennifer Aniston and Justin Theroux rarely make appearances together, so when the newly-engaged couple decided to take Jen's huge engagement ring for a spin, we took a second glance. But our double take wasn't just for Jen's rock (or Justin's always-inquisitive eyebrows) -- it was her plunging dress that stole the show.

To attend the LACMA 2012 Art + Film Gala on Saturday, the 43-year-old opted for a black silk gown with a wide-set neckline that practically reached her belly button. Thankfully, the plunging gown featured a sheer mesh overlay to prevent any wardrobe malfunctions (though we suspect there were more than a few close calls). Perhaps Jen's feeling sexier with her new man by her side?

This isn't the first time that Ms. Aniston's gone braless either -- it's kind of her thing. Chelsea Handler even physically pointed it out when the actress stopped by her show this month. Plus, it's not uncommon for celebs to wear red carpet dresses that require double-sided tape. But is this dress pushing the limits?

We think she looks glowing and happy, so we say: work it, Jen! What about you? Check out the photos from the event below and tell us what you think.
