How I Met Your Mother Season 100th Episode to Feature Rachel Bilson, Tim, Gunn, and Stacy Keibler

by POPSUGAR Entertainment 7

It's the night we HIMYM fans have been waiting for — the show's 100th episode! All the anticipation is due to the little hints about the special that have been leaked over the past few months. First we've got appearance of guest star Rachel Bilson, who may or may not be the mother (though she may have some stiff competition). Even if Bilson isn't Ted's soulmate, we can expect at the very least a clue about who he will end up with.

Bilson is hardly the only guest star tonight, though; Stacy Keibler plays a sexy bartender who may give Barney a chance — if he gives up his beloved suits. To help advise him on the question of identity is Project Runway guru Tim Gunn, whom I love almost as much as this show. Lastly, the episode will culminate with a grand musical number and the original song "Nothing Suits Me Like a Suit." So, how excited are you?!
