The Black Eyed Peas star interrupted a meeting between BBC bosses and the 'Spinning Around' hit-maker in a bid to convince the Australian pop singer to accept a role on the panel alongside fellow judges Sir Tom Jones and Kaiser Chiefs frontman Ricky Wilson.
Speaking to The Sun newspaper, Kylie recalled: ''I was considering it and I didn't I know what the answer was. Then I had a meeting in LA and will.i.am bombed the meeting.
''I had just one question to Will - how was the experience? He said he loved it, so I thought, 'OK, that's cool'.''
The 45-year-old singer admits she became overwhelmed with nerves and lost many nights sleep as a result of the pressure to make a decision, but looking back believes she made the right choice.
Kylie added: ''I lost sleep back then, I really felt a lot of pressure and I didn't know what the right decision was.
''My record company were really keen but I didn't buckle. I feel like it was the right decision now because this feels great, it feels like it's the right time.''
Meanwhile, will.i.am - who will appear as a judge for a third time when 'The Voice' returns on Saturday (11.01.13) - revealed he wasn't willing to sign up if Kylie turned down the offer, as he explained: ''I was like 'I can't make my decision but I guarantee you if Kylie says yes, I'm in.''
