Brody Jenner can't wait to be an uncle! The DJ couldn't contain his excitement on Wednesday when he posted a cute photo to Instagram of him and his brother Brandon cradling Leah Jenner's growing baby bump. Brody captioned the photo, "Uncle Brody is counting down the days!!!!! @brandontjenner @leah_jenner." And Leah and Brandon, who announced in early June that they're expecting a baby girl, are the cutest parents-to-be. In addition to posting a slew of sweet and sexy photos of Leah's pregnancy on Instagram, the world was also given a glimpse inside her whimsical and sun-soaked baby shower. See Brody's new photo above, then check out Leah and Brandon's Father's Day celebration with Caitlyn Jenner.
