Since virtually the beginning of the series, Ted has been pining for his slutty pumpkin on Halloween. So on the ten year anniversary of their initial -- and only -- meeting, fate and a friendly guy at the costume rental shop intervened and Ted found himself at her door on 'How I Met Your Mother' (Mon., 8PM ET on CBS).

Katie Holmes took on the iconic role of the slutty pumpkin, where we quickly learned that she will definitely not be the mother -- never mind that we've already met the mother's ankle in another apartment. The chemistry between the two was just disastrous, but the romance of the story kept Ted hanging on way longer than he otherwise would.

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.

Katie Holmes will play the oft-referenced but never before seen Slutty Pumpkin on 'How I Met Your Mother.'

According to Vulture, Holmes will make her 'HIMYM' debut in a Halloween episode in October. The character, who dressed as a pumpkin at a Halloween party in 2001, was introduced in the show's first season as a potential love interest for Ted.

'HIMYM' co-creator Craig Thomas called Holmes a "lovely" and "talented" actress. Holmes' last TV role was in Reelz Channel's 'The Kennedys' miniseries, and her last guest appearance on a scripted TV show was an episode of ABC's 'Eli Stone' in 2008.
