Jaylen Brown and Kysre Gondrezick sure look like an item ... the two pro basketball players pulled up to the ESPYs together arm-in-arm -- and even appeared to get ready for the event inside the same hotel room.
The annual sports award show is going down Thursday evening at the Dolby Theater in Los Angeles ... and the Boston Celtics star and the WNBA player were seen preppin' for the event at the Pendry in West Hollywood.
Check out a photo TMZ Sports obtained of the two on a balcony just hours before they hit the ESPYs red carpet together .
