The entire Trump family were at Mar-a-Lago Tuesday night for a double celebration, we’re told.

Spies at the president’s Palm Beach club say he, Melania, Ivanka and Jared Kushner, Eric and Lara, Tiffany and Barron all toasted Don Jr.’s birthday before ringing in the New Year together.

Also there were Jr.’s girlfriend Kimberly Guilfoyle, Fox’s Lou Dobbs, socialites Somers and Jonathan Farkas, Ava Roosevelt and Jean and Martin Shafiroff.
