Wowza did the temperature just spike in here? Or is it just Megan Fox and Kourtney Kardashian?

The Jennifer's Body actress - who is engaged to be married to singer Machine Gun Kelly - shared some behind-the-scenes Polaroids on Instagram from a joint photo shoot with the Kardashians reality star, during which the two posed sexily in their underwear for a SKIMS campaign published last September.

In the photos, snapped by hairstylist Andrew Fitzsimons, Fox and Kardashian are captured pressing their faces against each other, straddling one another, and modeling black pieces from Kim Kardashian's coveted shapewear line.
