Although the plastic surgery procedure is often done by patients undergoing gender reassignment surgery, the 64-year-old E! reality star says he "just never liked his trachea." You can see how his throat is much smoother in the new pics than before.
The Keeping Up With the Kardashians star also debuted a new hairdo: he's got ombre blonde ends, just like his daughters Khloe Kardashian and Kylie Jenner.
According to TMZ, the former Olympic champion hasn't filled his family in on why he's changing his appearance.
A source says no one on the show discusses the changes in Bruce and there's no plans to address them in the future.
Perhaps he's simply giving himself a post-breakup makeover since he and Kris Jenner announced their separation in October 2013 after 22 years of marriage.
What do you think of Bruce's new look?
