The pic is from Kylie's official twitter. I for one am excited because Greg did some fabulous tracks for X. All the Wow haters are soiling their panties yet again and I couldn't be happier! Greg has really evolved over the past few years as a producer since working on X so the results should be amazing!
Greg produced Wow, No More Rain, Do It Again, Carried Away, Deepest Blue, and don't forget his amazing remix of Can't Get You Out Of My Head!
