The duo was connected at the hip as they left The Nice Guy, where Gigi Hadid had her birthday party -- and earlier in the night they were all hugged up at Naomi's event for her new book. Btw, the photo book retails for $1,750!
But you gotta see this video because ... if they're not REALLY a couple, they're doing a REALLY good job acting like it. Also, how cool is Lenny? Who else could get Naomi to ride shotgun in an old jeep blanketed in massive amounts of bird crap?
