The twosome headed to Kate Hudson's annual costume bash with baby dolls in tow, paying homage to Brangelina's red carpet appearance in Cannes a few years back when Ange was preggers with Knox and Vivenne.
Baby bump-sporting Jen donned a green flowing dress reminiscent of Angie's famed Max Azria maternity number, while her actor beau, Jarod Einsohn, wore a wig and sunglasses.
So who else was in attendance at Kate's besides "Brangelina"?
Jen and Jarod weren't the only guests who masqueraded as other celebs.
Gwen Stefani chose a Cinderella getup, Jessica Alba wore a witch costume, David Arquette made like Elvis, Emma Roberts was a Playboy bunny, and her boyfriend, Chord Overstreet, came as a lumberjack. As for the hostess herself, Kate was a shot girl.
Sounds like a freakishly good time to us!
