"They wanted to celebrate their new home and their sixth anniversary by renewing their vows," a source tells PEOPLE. "They're excited about their new life together as a family in California and wanted to kick it off with a great party."
Among those on the 200-guest invitation list, says a source, are Tom Cruise and Katie Holmes, and Brad Pitt and Angelina Jolie.
"Jen is very excited about sharing her special night with her family and friends," the source adds. "The party will be spectacular. Guests will enjoy dancing until the morning hours."
Like the invitation, the party features an art deco-theme with the colors gold and silver. The card, which features a large gold key, reads, in full:
A NEW BEGINNING
PLEASE JOIN US AS WE
"WARM OUR HOUSE"

Renewing their vows is becoming something of a tradition for the couple – who got the ball rolling for the first time in 2008. That year – which also brought the February birth of their twins, Max and Emme – they also did it up big by joining New York Mets outfielder Carlos Beltran and his wife Jessica for a joint vow-renewal ceremony in Las Vegas.
As for their humble abode, it is anything but. Purchased by the couple earlier this year for just under $10 million, it is spectacular and ultra private. All told, within its three acres there are nine bedrooms, 12 bathrooms, panoramic city views, rolling lawns, a swimming pool and a tennis court. Also inside: a fabulous 20-seat theater, a recording studio and a wine cellar.
