DeGeneres has been scaring celebrities for years, and some skeptics may assume the stars knew the host was going to shock them on national television — but their genuine reactions tell a different story.
Ahead, a history of DeGeneres' best celeb scares. No famous person is safe.
Selena Gomez
Not once. Not twice. But three times. You'd think it'd get old, but nah.
Cameron Diaz
Let's see how Diaz reacts when a character from her first movie surprises her.
Megan Fox
In any other circumstance, a man dressed as a giant banana would be a joyful character.
Steve Carell
To be fair, he scared her first.
Oh, Swiftie. Ellen got her a solid eight times.
Miley Cyrus
Miley was all "I'm not scared of anything anymore." Then Ellen was all "challenge accepted."
Julia Roberts
How one manages to still look so beautiful and not a mess is beyond us.
Pink
Pink seems like the kind of woman who wouldn't scare so easily. Not the case.
That's what you get for trying to impersonate Sofia Vergara.
Channing Tatum
This isn't her trademark surprise tactic, but watching Tatum face his lifelong fear of porcelain dolls is pretty incredible.
Adam Levine
You probably shouldn't openly discuss how you hate scary things with Ellen.
Having already been the victim of an Ellen scare herself, Julia Roberts teamed up with Ellen to spook Martha Stewart.
Jake Gyllenhaal
Annnnd her most recent success with Jake Gyllenhaal.
