Just days after making it through to the Judges' Houses, singer Tom Bleasby is leaving The X Factor.

The 19-year-old wowed the judges with his first audition back in August, and on Sunday was chosen to be one of Nick Grimshaw's final six contestants.

But after referring to Sunday's Six Chair Challenge as "the worst experience of my life," Tom took to Twitter last night to confirm he was leaving the show.

"Due to personal reasons I have decided to withdraw from The X Factor," he wrote.

"Thank you to all the judges, especially Nick for his belief in me. 

"I'm not stopping singing, the X Factor is just one path…one that wasn't right for me."

During Sunday's show, Tom eventually secured a place in the final six after being swapped out by Nick in the Six Chair Challenge and then brought back in.

Despite his shock exit, BBC host Nick offered his support to Tom via Twitter last night:

In his exit interview with ITV, Tom said he simply wasn't ready for the intense pressure of the show.

The singer, who sang on The Ellen DeGeneres Show with Jessie J shortly before his first X Factor appearance, admitted his rise to stardom had happened extremely quickly.

"I’m quite a relatively new singer, back in March, I was singing in my bedroom, so I’ve never took to live performing very well.

"I just don’t know if I felt vocally ready to take on the competition and the pressure."

Jessie J also tweeted a message of support to Tom last night, telling him: "You didn't just trust your instincts, you followed them."
