Surely not... tv.com has posted a news item about the upcoming X-Factor finals in Australia...

"The three remaining contestants will be given a rare opportunity to perform a duet with international singing stars Jamiroquai, James Blunt and INXS."

So it looks like Jay could be doing a duet on the show this coming weekend... Just having a think here, has Jay performed many other duets in the past?  I can think of Bad Girls at the Brit Awards in 2002 (and have been reminded of Jay/Diana Ross at the Brits) but are there any others...

UPDATE: It looks like Jay's going to be doing a duet with finalist Sally, as shown in a promotional commercial for the show that is on YouTube.
