However, the 22-year-old actress took things to a new "low," showing up at the notoriously geeky Comic-Con convention in San Diego to promote her upcoming film "Green Lantern" wearing a top that barely covered her, um, lanterns.
Lively and her "Green Lantern" co-stars Ryan Reynolds, Peter Sarsgaard, and Mark Strong sat down for a panel discussion and we're pretty sure the audience was having a hard time concentrating on what was coming out of Lively's mouth, being that her bust was spilling out of a white futuristic top by Preen that plunged down almost below her breasts then widened so that a nip-slip was almost inevitable.
And the the chest-level table the stars were sitting at didn't help the situation.
In any case, Lively kept the rest of the look tame, pairing her revealing northern hemisphere with black silky high-waisted pants also by Preen (cinched with a black belt), black-and-white heels and, sticking with the "Green Lantern" theme, emerald drop earrings by Lorraine Schwartz.
We commend her for avoiding this blotchy chest situation from last year's Angel Ball.
