What a dutiful fiancee!

Jennifer Aniston left no stone unturned on Saturday when the actress threw her soon-to-be hubby a huge party for his 42nd birthday!

The party took place at the couple's newly-renovated $21 million, 8,500-sq.-ft. home and included a large shipment of champagne and great food from her personal chefs while DJ Samantha Ronson provided the popular tunes to keep the good times going.

Guests for the soiree included Tom Cruise, Laura Dern, Lake Bell, Ben Stiller, Christine Taylor, Dax Shepard, Kristen Bell, Ellen DeGeneres and Portia de Rossi to new a few of roughly 75 in attendance. Quite the star studded affair!

And seeing as how the party took place on the one year anniversary of their engagement, she really went all out!
