The latest stars with wedding bells on the cards are Olivia Wilde and Saturday Night Live's Jason Sudeikis. The celebrity couple have been dating since November 2011.
A source told people: "They are so excited, and very, very happy."
Olivia has previously said she fell "blissfully, hopelessly, wildly in love" with Jason after meeting him.
With Keira Knightley, Miley Cyrus and Jennifer Aniston also engaged to their beaus, we could be in for a seriously star-studded list of weddings in 2013!
