President Obama and the DNC Hire Jamie Foxx for $10k/Ticket Party!

President Obama could be blaming it on the a-a-a-a-alcohol this weekend -- 'cause he's gonna be partying with Jamie Foxx at a ritzy celebrity event ... TMZ has learned.

The DNC is throwing one of those big ticket fundraisers on Saturday in Pacific Palisades where the Prez will be pressing the flesh and working the room. The original invitation went out saying, "Musical guest TBD" ... but our DNC sources tell us Foxx will be the entertainment.

If you wanna roll VIP -- as in get a photo with Obama and prime seating for the concert -- it'll cost you $10,000! You can get in the door though for a mere $1,000 ... no pic included.

The exact location is only listed as a private home, until you fork over the dough for a ticket.

Let's hope Jamie's turn as POTUS in "White House Down" doesn't come up in conversation. For Jamie's sake.
