Kristen Bell peed into a jar at the Oscars!

Looking awesome during awards season totally has its price. Kristen Bell found this out the hard way when she ran into a bit of a situation with her custom Roberto Cavalli gown. Let’s call it a "bathroom malfunction".

That skin-tight mermaid dress may have looked amazing on the petite Veronica Mars star, but was it comfortable?

"Nope," the 33-year-old revealed on US talk show Live With Kelly And Michael And I didn’t realize that until I got into it."

Uh oh.

In her own words: "There was a situation… there was a Mason jar involved… Like you guys haven’t peed into a Mason jar before in a huge ball gown!"

Who hasn't?

But seriously, we wonder how many of these other Oscars starlets had similar bathroom issues?
