Johnny Manziel -- You Got Served ... Hit with Lawsuit While Clubbing (VIDEO)

Johnny Manziel got hit square in the chest with a lawsuit Wednesday night -- getting served with legal papers while clubbing in Hollywood ... and TMZ Sports has the footage.

We broke the story, Manziel is being sued for allegedly throwing a drug fueled bender at a rental home in the Hollywood Hills earlier this year ... and last night, the process server found him outside The Nice Guy.

But Manziel didn't let the lawsuit stop his party plans -- he got right inside his Rolls-Royce and moved over to Warwick ... where he partied (and left) with a beautiful lady.

By the way, interesting timing on the party plans -- earlier in the day, Manziel's lawyer issued a statement saying he was still focused on playing in the NFL.
