Like it or not, The Slutty Pumpkin has been revealed.

First mentioned way back in Season 1, The Slutty Pumpkin has been a 'How I Met Your Mother' legend. Ted (Josh Radnor) met Naomi (Katie Holmes) at a Halloween party in 2001, but lost her number and has spent years waiting for her. Now she's back ... and very affectionate.

Here's how CBS describes the episode: "'The Slutty Pumpkin Returns' (Mon., Oct. 31, 8PM ET) -- Ted finally meets his mystery girl in the Slutty Pumpkin costume. Meanwhile, Barney learns he is part Canadian, and Lily has pregnancy brain."

Check out videos and photos of Holmes as The Slutty Pumpkin below!

The notorious Slutty Pumpkin has been part of 'How I Met Your Mother' lore for years, but now, after hearing about the mysterious stranger who stole Ted's heart back in 2001, we finally get to see her.

Here are some photos of guest star Katie Holmes making her debut as the Slutty Pumpkin on this year's Halloween episode. Don't Ted and Slutty Pumpkin look cute together?

Honestly, we don't think she looks that slutty, but the costume is pretty short, and there are some very strategically placed holes in the front, which might just have made for an interesting time with Ted's Hanging Chad (remember them?) outfit.
