It's that time of year again ... All the single ladies and gents are coolin' off and are ready to chill with the idea of cuffing up with other hotties ridin' solo. There's nothing taboo if you're a party of one, however it's a PDA rager for these hot doubles!

Dynamic duos like Selena Gomez and Benny Blanco literally, couldn't 'keep their hands to themselves', Nick Jonas and Priyanka Chopra took off their pants and kept cozy in France ... and Kelly Ripa and Mark Consuelos are still hot for each other after 28 years of marriage.
