Rihanna And Travis Scott Sloppy for Each Other

EXCLUSIVE

Rihanna and Travis Scott were like two dogs in heat early Friday morning at her Fashion Week after-party ... making out, grinding and dry humping each other as if no one was watching.   

Fact is ... they were openly and notoriously affectionate in front of a room full of people.

The two have been hanging out in NYC this week, fueling rumors they've hooked up ... but this video pretty much confirms it.
