X Factor's Ella Henderson And George Shelley Go Public

A new couple have emerged from this year's X Factor, as Ella Henderson and Union J's George Shelley have gone public with their budding romance.

Public favourite Ella and boyband member George were rumoured to be getting on very well behind the scenes on the show, but their relationship is now official after they were snapped strolling around London together.

The couple looked cosy on their romantic little wander, with Ella wrapped up in a puffer jacket and George in a red hoodie and matching hat.

Despite being only 16 years old, Ella has wowed the judges each week with her impressive vocals, and won plenty of fans for her distinctive vintage style.

And Union J may be hoping to copy the success of fellow X Factor boyband One Direction after making it so far in the programme, already racking up over half a million followers on Twitter.

A source told the Sun: "Ella and George are the sweetest couple. It's so lovely to see them together now they’re not denying it. They are thrilled they’ve both got far enough to get on the tour. It means they can spend more time together next year."
