Luol Deng -- Here For The Deng Party ... Celebrates Lakerness At Hollywood Night Spot (VIDEO)

Luol Deng celebrated his arrival in Tinseltown the way any new Laker should ... thots, bottles and models ... hitting a Hollywood night spot and turning up Tuesday night.

We got Deng leaving 1 OAK in West Hollywood -- a spot regularly frequented by the Kardashians, Beibers and Rihannas of the world -- around 2:30 AM, telling us he definitely had a great time.

Deng wasn't the only freakishly tall guy turning up ... Andre Drummond and Jimmy Butler were also there ... and with the money the NBA's giving out these days, we're guessing a lot of people drank free.
