Most weddings have save-the-dates, invitations and the whole she-bang, and in Hollywood, you get a few massive, headline-making affairs (please see: Kimye鈥檚 wedding). With the more private celebs, there鈥檚 a huge trend sweeping Hollywood right now with getting married in secret and the latest pair to shock their friends and fam is Jennifer Aniston and Justin Theroux! According to Entertainment Tonight, the pair tied the knot during a secret ceremony last night. The couple met on vacation in 2011, got engaged in 2012 and wedding speculation has been rampant ever since. It鈥檚 no wonder they decided to keep it under wraps.

Jennifer and Justin not only surprised us, it sounds like they may have surprised their guests, including singer Sia, Ellen DeGeneres, Chelsea Handler, Friends friend Lisa Kudrow and even couple Emily Blunt + John Krasinski. The night was actually masked as a birthday party for Justin.

The super private celeb couple are the latest in partaking in this hush hush wedding trend. Ashton and Mila secretly wed over Fourth of July weekend. Blake Lively and Ryan Reynolds were another A-List pair who decided to keep their nuptials on the DL. Leighton Meester and Adam Brody鈥檚 wedding details are still a closely guarded secret, even though they have a little one on the way.

Congrats, Jen and Justin! And, here鈥檚 another reason to make sure to RSVP to every invite you get these days.
