Photos: Alexander McQueen FW 11/Roberto Cavalli FW 10

Though the two top models featured in these ads are definitely among the hottest, we don't think they've got temperatures high enough to spontaneously combust. The people at McQueen and Cavalli seem to disagree, however. While the David Sims ad with Raquel Zimmerman is from fall 2011, and Mert Alas and Marcus Piggot's Gisele Bundchen feature is fall 2010, they are strangely and strikingly similar.

From the beautiful, musty grey lighting to the explosion happening in the background, it seems like Alexander McQueen may have borrowed a little lighter fluid from Roberto Cavalli on this one. Take our poll to tell us which model detonation you like best.
