Miller, 27, revealed during an appearance on the Tonight Show with Conan O’Brien that she burned her boobs while making the action flick.
The star explained, "I burnt my boobs in an explosion that went wrong. Channing Tatum was carrying me down an exploding corridor and a spark went down my rather large cleavage at the time. But they’re fine now, no lasting damage."
O’Brien then tried to look for a scar, but the actress refused, joking, "They’re fine, let’s not dwell on it."
G.I. Joe: The Rise of the Cobra is now playing in theatres.
