On Monday, the 45-year-old was filling in for Erin Andrews on Dancing With The Stars, when she got pretty frightened! The brunette beauty was interviewing Tamar Braxton and her partner Val Chmerkovskiy when a creepy clown snuck up behind her!
The actress was so spooked that she literally fell to the ground! LOL! Well, what else would you expect during the show's Halloween week?!
Ch-ch-check out Leah's HIGHlarious tumble of terror (below)!
