Justin Theroux loves to surprise Jennifer Aniston—but not with flowers and candy! In an interview with Ellen DeGeneres airing Thursday, Aniston reveals that her fiance loves to pop out from unexpected places in their home, and that she falls for it every time.

"He calls it 'trickery.' But he's constantly hiding behind drapes. And I'm constantly scared," Aniston says of Theroux. "It doesn't get old on me."

Unfortunately for Jen, Justin definitely has the advantage here, because she's terrible at scaring people! Watch her try—and fail—to punk Ellen in this clip

Speaking of Jennifer Aniston and surprises, what's happening with that much-anticipated wedding? For obvious reasons, Jen and Justin are keeping the details on lockdown. Turns out, even she doesn't know all of them! 

"I don't have a dress. That's something that will probably come together at the last minute. I like to be very spontaneous," Aniston told Extra at the premiere of the new Lifetime movie she produced, Call Me Crazy.

That's not to say that the stress isn't getting to her. At the same event, she joked to E! News that wedding planning "might make me crazy." Maybe Justin Theroux should pop out from behind the curtains to relieve some of the tension!
