Bruce Jenner's much awaited Interview with ABC's Diane Sawyer is been teased in bits but does the reality star sound confident with his decision to change from a male to a female?

The former Olympic champion seemed quite exhausted answering series of daring questions from the TV host as she tries to explain how he feels after his transformation.

Sawyer invites Bruce to become 'her' for a moment and to ask any question he thinks she would ask him.

Bruce pauses before saying, ''are you gonna be ok?''. So Sawyer then ask the same question to the star: ''Are you gonna be ok?”

Bruce responses, ''Yea.. I hope I'll be ok... I feel like I'm gonna be ok cause 2015 is gonna be quite a ride''.

Well, watch Bruce try to tell his story in his teaser.
