Bruce Jenner - H 2015

Miley Cyrus, Ellen DeGeneres, Rob Lowe and Ariana Grande were among those weighing in on Twitter.

Bruce Jenner came out as transgender during an interview with ABC's Diane Sawyer on Friday, leaving Hollywood abuzz.

"For all intents and purposes, I am a woman," the former Olympic gold-medal winner said during the 20/20 segment. "My whole life has been getting me ready for this."

A number of his family members shared their thoughts on Twitter following the sit-down. Stepdaughter Kim Kardashian wrote that Jenner's "honesty has opened the doors for others to be courageous and live an authentic life," while ex-wife Kris Jenner tweeted: "Not only was I able to call him my husband for 25 years and father of my children, I am now able to call him my hero."

Many Hollywood notables weighed in on social media as well, and their tweets can be seen below.
