Bruce, 65, announced his decision to become a woman during a tell-all interview with ABC's Diane Sawyer and while the show was being broadcast, Kris took to Twitter to send a vague message.

The 30-year-old star posted: "Man, I'm glad I got out when I did. #Gottadoyou"

Subsequently, the basketball player, who was married to Kim Kardashian West from 2011 until 2013, was subjected to a torrent of abuse from online users, many of whom accused him of being insensitive and ignorant.

However, Kris has since insisted that was never his intention and his original tweet was badly misinterpreted.

He said: "I have and always will support Bruce hence #Gottadoyou. Now recognize I was too vague and sincerely apologize for the way this came across. (sic)"

The Washington Wizards player added: "#FullySupportBruce"

Meanwhile, Bruce's 17-year-old daughter Kylie Jenner has taken to Twitter to declare her support for her dad.

She said: "Woke up still in awe... I've never been more proud of you, Dad!!!!!! (sic)"

During the interview, Bruce said that "for all intents and purposes, I'm a woman".

He added: "I have the soul of a female and my brain in much more female than it is male, as of now I have all the male parts."
