Kate Hudson is thinking pink! The expectant mama appeared on Today this morning to promote her new movie Something Borrowed (and reveal her engagement) telling Matt Lauer about her "scientific" way of determining her baby's gender. Using the popular pendulum method of dangling a ring (or weighted object) from a string above her belly, Kate thinks she's having a lil girl. She'll know for sure soon enough – Kate also told the host that she's in her third trimester. See her explain the pendulum method, and why she thinks she's carrying a mini-Goldie Hawn below.
