Aside from the bride and groom, Bruce Jenner has the most crucial role to play in today's Kardashian/Humphries Nuptials. So how is Kim's stepfather feeling mere hours before walking her down the aisle?

"Not nervous at all," Bruce Jenner told ET, before playfully adding, "All I have to do is walk her down the aisle [and] I was once know to be athletic."

But adding the 6' 9" NJ Nets star to the clan does pose a problem for Kourtney Kardashian -- she's now surrounded by tall people! Jenner (who is 6' 2") joked to us that Kourtney was wearing the highest heels imaginable at last night's gathering and still found herself dwarfed!
