Celebs Hit White House for President Biden's First State Dinner

Hollywood is back at 1600 Pennsylvania Ave., where President Biden's finally getting to entertain a foreign dignitary -- French President Emmanuel Macron -- as well as famous supporters.

Thursday night marks the return of swanky state dinners ... as the COVID pandemic forced Biden to cancel such events for the first 2 years of his administration, but the celebs are flocking back to the White House. No shocker.

John Legend and Chrissy Teigen are in the house, along with Stephen Colbert, Julia Louis-Dreyfus, Jennifer Garner and Ariana DeBose.

Apple CEO Tim Cook scored an invite too ... he's having a pretty loaded week, just yesterday he was meeting with Elon Musk at Apple HQ in Cali, smoothing things over with Twitter.

All the pomp and circumstance is for France ... Biden's working to repair the U.S. relationship with the European power.

These celebs are among 300 guests at the black-tie dinner, with folks dining on the best cheese America can offer Macron ... plus Maine lobster, beef with shallot marmalade and triple-cooked butter potatoes.

There's live music too ... Dr. Jill Biden booked Grammy-winning musician and composer Jon Batiste, in part because he's from New Orleans, which Jill notes "has been shaped by both French and American culture."
