Skipping the parties preceding the White House Correspondents' Dinner, Reese Witherspoon and hubby Jim Toth opted instead for a double date with some famous pals!

Joined by Kate Hudson and fiancé Matt Bellamy, along with Sports Illustrated swimsuit cover model Kate Upton and a talent agent, the party of six dined at Café Milano in Georgetown on Friday night for three hours.

"They seemed to be having lots of fun," an onlooker tells PEOPLE, adding that Witherspoon laughed throughout the meal and appeared to be in great spirits, while displaying her baby bump in a black dress.

On the menu for the pregnant actress? Fresh baby artichoke, salad in a lemon vinaigrette and spinach fettuccine with veal Bolognese sauce.
