It may be a mere 15 seconds in length, but boy has the internet gone coo-coo-bananas for it today. There has been so much build up regarding Bruce Jenner's "goodbye to Bruce" themed interview with Diane Sawyer, we're not sure what the internet is going to do after the it airs in full - apart from post snippets from it and then wait for photos of Bruce in his new guise to appear somewhere - we'll hazard a guess and say TMZ. 

In case you're unable to view the video, Bruce says: "My whole life has been getting me ready for this." That is all.

Comments under the YouTube teaser include: "Are we 100% sure, that he is ACTUALLY transitioning??? I'm not believing it, until I hear it from Bruce himself tbh. If true, I just CAN'T believe this is actually happening. It was all just gossip and speculation in blind items and whatnot. Just.. WoW."

Yes, 'Nilani', this is happening. 

The full two-hour interview is due to air on ABC on Friday, April 24th, at 9 p.m. ET.
