Katy appeared alongside Amy Poehler, who was hosting the show, and former cast member Maya Rudolph in a hilarious “Bronx Beat” sketch.
In the skit Katy plays a teenager that developed over the summer.
“Honey, you’ve exploded! Kaboom!,” Amy and Maya’s characters said. “Looks like this show is brought to you by the number 38 and the letter double D.”
It's actually a pretty hilarious sketch, check out Katy and her double DD's below...
