X Factor hopeful Nathan Fagan-Gayle has already met Tulisa, after supporting her on tour just last year.
The 25-year-old, who is also known as Starboy Nathan, has also enjoyed two studio albums and even two top 40 singles before now.
Less than 18 months ago, Nathan was in the charts with his new single Diamonds, which charted at 23.
And Nathan has released a string of other singles on various record labels, going as far back as 2005.
The singer, who has made it through the judges' houses stage of this year's competition, also has plenty connections with X Factor stars.
Nathan was a support act for former X Factor runners up JLS on their second arena tour, and also supported X Factor judge Tulisa on N-Dubz's Love.Live.Lie tour in 2011.
At his audition, Nathan wowed the panel with Marvin Gaye’s ‘Lets get it On’ to sail through to bootcamp.
Gary Barlow told him: "Nathan I’ve got to tell you, you have an amazing voice!” while Tulisa gave him a "big yes".
At bootcamp Nathan impressed again with a performance of Labrinth's Earthquake before wowing the panel and audience in Liverpool with some body popping.
This year the rules have been relaxed on acts like Nathan, allowing more professional artists to audition for the show.
The X Factor 2012 judges' houses air this weekend on Saturday and Sunday on ITV1.
