'How I Met Your Mother' revelation: Katie Holmes is the 'Slutty Pumpkin'

Shockers abound in Season 7 of "How I Met Your Mother."

Just days after the season premiere return of Season 1's cupcake girl, Victoria (Ashley Williams), the identity of the elusive "Slutty Pumpkin" has been revealed.

First reported by Vulture, the elusive character first mentioned in Season 1 will appear this year in the form of Katie Holmes.

"Katie is a lovely and talented actress," co-creator Craig Thomas tells Vulture, "which is why we've saved for her perhaps the most classily named character in our show's history."

"The Slutty Pumpkin," also the name of the series' sixth episode, was a potential love interest Ted (Josh Radnor) met at a 2001 Halloween party and never saw again. She's since been mentioned several times -- and cannot possibly be the mother.
