The 28-year-old singer admits that he skipped a line because of nerves...

James Arthur made an epic comeback on The X Factor last night.

The 28-year-old appeared on the results show to perform his track Say You Won’t Let Go, which Simon Cowell had earlier explained is the 41st #1 released by an alum.

It’s safe to say that James impressed, with Tweets including: ‘James Arthur on X factor last night 😍 omg,’ and: ‘Was delighted to see the very cute and talented James Arthur on X factor. He’s so brilliant 💙 [sic].’

However, some keen-eared viewers couldn’t help noticing that he’d, er, forgotten his own lyrics. Eep.

Halfway through the performance, he missed the first line of the second verse, which is supposed to be: ‘I wake you up with some breakfast in bed’.

Instead, he twice sung the lyric: ‘I’ll bring you coffee with a kiss on your head’.

One message read on Twitter: ‘James arthur forgetting his own words… 👏👏 welldone pal #XFactor,’ while others said: ‘James Arthur totally just got the words wrong then.. awks #xfactor,’ and: ‘James Arthur proving that even professional singers get their words wrong! #XFactor [sic].’

However, James wasn’t afraid to admit to his mistake, explaining on his own page: ‘That was the most nerve wracking thing I’ve ever done so apologies for the pitchyness and incorrect lyrics but thank you so much everyone ❤️.’

A pretty brave statement to make, eh? And we think he pulled it off like a total pro.

James’s recovery wasn’t the only thing people were impressed with. They also praised his mention of World Mental Health Day, which is taking place today.

One fan Tweeted: ‘#JamesArthur well done for raising awareness of #mentalhealth yesterday on #XFactor That’s how fame should b used!’

Another said: ‘Hopefully #JamesArthur on #xfactor will inspire other people and celebrities to talk openly about mental health and spread awareness #glitch [sic].’

We couldn’t agree more. It’s great to have you back, James!
