Justin Theroux and Jennifer Aniston attend the 2015 Oscars

Jennifer Aniston and longtime boyfriend Justin Theroux are finally husband and wife. The couple married Wednesday (Aug. 5) in a top-secret ceremony at their Bel Air mansion, Us Weekly confirms.

Celebrity attendees included Lisa Kudrow, Emily Blunt, John Krasinski, Ellen DeGeneres, Lake Bell, Scott Campbell, Terry Richardson, Howard Stern, Sia, Chelsea Handler and Jennifer Meyer.

TMZ reports the couple disguised the event as an elaborate house party complete with a cake featuring puppet versions of themselves. A pastor carrying a Bible was also seen walking into the home. The ultra-private pair went all-out to keep the big event under wraps, hiding anything related to the wedding set up in a big shed on the property.
