Who will make it to the altar first? Jennifer Aniston and her new fiance Justin Theroux, or Brad Pitt and Angelina Jolie?
Jen announced her engagement to Justin Sunday night, just four months after Brad and Angie told the world they would finally marry.
Oddly enough, the engagement came the very weekend that many news outlets speculated that Brad and Angie would secretly marry in France (they didn't as far as we know).
But now many are wondering what the story is with Jen and her hubby-to-be.
Us Weekly put together a timeline of the couple from meeting to planning their "I do's."
2007: Jen met her future love on the set of "Tropic Thunder"; Justin co-wrote the film with Jen's longtime pal Ben Stiller. "I remember thinking he was very dark. At first you think he could be like a serial killer, but he is actually the nicest person in the world," Jen said.
