DeSean Jackson turned 30 years old Thursday ... and he celebrated by raging his face off at a D.C. nightclub ... chugging champagne, taking shots and rocking more jewelry than Tiffany and Co.
The Washington Redskins superstar hit up Sax -- a super gaudy, gold-everywhere, over-the-top club -- where he celebrated with the likes of Wale and 'Basketball Wives' star Laura Govan.
Jackson broke out his fancy jewelry and his fancy Maybach for the occasion and turned all the way up.
Our advice ... HYDRATE! Just 3 days 'til DJ takes on the Arizona Cardinals.
