Things got hot and heavy between Rihanna and her new mystery flame.

The "Wild Thoughts" singer was photographed by TMZ while locked in a passionate kiss with a male companion, who reports have yet to identify. The picture was taken in Spain, where the pop star is in the middle of a holiday abroad. They're supposedly staying at a posh villa, and by the looks of this picture, it's clear that they can't keep their hands (and tongues) to themselves.

This would explain why she was a no-show at the BET Awards this past weekend too - looks like she had something much more important on her docket. Only time will tell if she'll be making these make out sessions a regular thing with the guy in question.
