Julia Roberts proved she’s down for some silliness when she made an appearance on “Ellen” this week and scared the crap out of Julia Louis-Dreyfus.

It was all part of Ellen’s plan to make nervous wrecks of her guests, and it definitely worked this time. Ellen got Julia as she was coming out of her dressing room, then Roberts jumped out of a closet and double whammy-ed her. Good thing the former “Seinfeld” actress is such a good sport, although she admitted she wasn’t happy about being seen on hidden camera with no makeup.

After some tongue twisters involving repeating the name “Julia”, the ladies showed the clip to the audience and got quite a few laughs at Louis-Dreyfus’ reaction.
