One thing about Barack and Michelle Obama — they sure know how to par-tay!

They held a final bash at the White House on Friday, which continued until 4 a.m. on Saturday morning.

And of course, celebrities showed up in droves.

Like Tom Hanks . . .

. . . John Legend, his wife Chrissy Teigen, and Jerry Seinfeld. . .

. . . and basketball greats Magic Johnson and Charles Barkley.
