Watch: Bruce Jenner’s transformation to a woman that is breaking social media

Caitlyn Jenner, the transgender Olympic champion formerly known as Bruce, unveiled her new name and sexy look on Monday in a Vanity Fair covershoot, drawing widespread praise and smashing a Twitter record. Lesbian, gay, bisexual and transgender campaigners and many well-wishers welcomed the high-profile debut, as did the 65-year-old Jenner's family, which includes the media-savvy celebrity Kardashian clan. "I'm so happy after such a long struggle to be living my true self," Jenner wrote in her first tweet after the magazine released the July cover photo by celebrity photographer Annie Leibovitz.
