We'd be scared too! 

Can you believe Cameron Diaz was just 21-years-old when she filmed "The Mask" back in 1994?! Lucky for the actress, her very first role was a huge hit.

Cameron sat down with Ellen DeGeneres on Thursday's "The Ellen DeGeneres Show," where she opened up about working with Jim Carrey on the fantasy flick 20 years ago.

20 years ... let that sink in.

The talk show host also planned a pretty awesome surprise, too. Check out the video above to see Cameron's hilarious reaction when DeGeneres recruits the help of a "Mask" lookalike!

We love the 41-year-old's scream -- how cute is she? Clearly, Jim's character still scares her, even today. 

While it's been nearly 20 years since the blonde beauty starred in the crime comedy, she still looks like the spitting image of her younger self!
