The Britney Spears era on The X Factor has begun – and we love it!

The mother-of-two was tested in her debut alongside fellow newcomer Demi Lovato, and incumbents Simon Cowell and L.A. Reid, when she assessed the talent of Don Philip, a 32-year-old vocal coach who sang a duet with her on the track I Will Still Love You from her breakout album, 1999′s …Baby One More Time.

Don, who was very emotional on the big night, told Britney, "I never thought I'd see you again," before detailing his battles with self-esteem that have stalled his singing career.
