Lewis Capaldi made quite the surprise as he crashed the stage a recent The Vamps show, despite his ongoing Tourette's struggles and taking a break from touring.

The 26-year-old singer made a surprise appearance to support his fellow musicians during their Kew The Music show in London on Wednesday (12 July).

As the crowds screamed in delight, Capaldi was seeing running on-stage and hugging frontman Brad Simpson during the performance of 'Risk Of It All'.

The Scottish singer grabbed Brad's microphone before he appeared to sing - but he couldn't be heard over the audience's excitement.

Fans were, of course, delighted, with one captioning a video posted to Twitter: "Best surprise ever."

Lewis is apparently a big fan of The Vamps and bandmates Connor Ball, Tristan Evans and James McVey, and previously shocked the band by singing the lyrics to one of their lesser-known album tracks as he approached them at an afterparty.

Vamps member Connor told the Celebrity Search Engine podcast: "We were at this afterparty with Lewis Capaldi and we were just chatting with him.

'We were just having a normal conversation and then, out of nowhere, he started screaming in mine and Brad's ears this album track, off our first album. So like, not even a single, he just loves the song!"

Last month, the 'Someone You Loved' singer took to Instagram to announce he was 'taking a break from touring for the foreseeable future' to 'adjust to the impact' of his condition and get his 'mental and physical health in order, so can keep doing everything I love for a long time to come'.

The Scottish singer was forced to cancel all 24 shows for his upcoming Broken by Desire to Be Heavenly Sent tour.

The move came just days after he struggled to finish his headline set at Glastonbury - though he powered through his Glastonbury pyramid stage set like a champion on 24 June.

After performing 'Bruises', he admitted he was having voice issues with his tics, telling the crowd: “I’m going to be honest everybody but I’m starting to lose my voice up here, but we’re going to keep going and we’re going to go until the end.

“I just need you all to sing with me as loud as you can if that’s okay?”

Fans were unbothered by Capaldi's announcement though, and helped the singer finish his song lyrics throughout the set in what turned out to be a moving performance.

He continued to apologise to the crowd and the Eavis family - who organise Glastonbury - for his voice starting to go.

Before his final song, Capaldi told the crowd: “I recently took three weeks off just because I’ve been non stop the past year and I wanted to take a wee break from my head for my mental health.

“I wanted to come back and do Glastonbury because it’s obviously so incredible so I just want to thank you all for coming out.

“I was scared but you’ve really made me feel at ease so thank you very much for that.”

Capaldi added: “I feel like I’ll be taking another wee break over the next couple of weeks so you probably won’t see much of me for the rest of the year maybe even.

“But when I do come back, when I do see you, I hope you’re all still up for watching.”
