Jake Paul Announces Tommy Fury Fight Date, December 18!

Mark your calendars ... Jake Paul and Tommy Fury will officially take the ring in December -- with the YouTube superstar announcing the fight date Friday.

"Pucker up Timmy, it’s time to kiss ur last name and ur family’s boxing legacy goodbye," Jake said on Twitter minutes ago.

The epic showdown is set to happen at Amalie Arena in Tampa Bay ... and Jake is vowing to hang out with some local celebs after coming away with the win.

"DEC 18th Im changing this wankers name to Tommy Fumbles and celebrating with Tom Brady."

Of course, Jake has previously claimed Tommy will have to legally change his name if he loses ... which he's told us he's not sweating at all, 'cause Fury is guaranteeing to put Paul into retirement.

Jake is 4-0 with wins over Nate Robinson, Ben Askren and Tyron Woodley ... but this is his first fight against a boxer.

Fury -- heavyweight champ Tyson's lil' bro -- is 7-0.

After months and months of going back and forth, it's finally happening ... and we legitimately cannot wait.
