Glasgow gig goers were stunned to see Louis Theroux make an appearance at Stormzy's OVO Hydro show.
Louis is currently joining Stormzy on his tour as the first subject of his new six-part BBC Two documentary celebrity series.
With a working title 'The Louis Theroux Interviews', the series will see him interviewing some of the most iconic names in entertainment.
Stormzy will be the focus of the first episode, as Theroux joins him on tour and at home “for an in-depth and personally revealing encounter” with the British rapper.
The remaining episodes will each feature a different guest, which are yet to be announced.
Fans went wild after one eagle-eyed attendee spotted the famous documentarian bopping along to the rapper in the crowd.
One commented: "This is exactly how I imagined him at a concert".
"My guy Louis loves rap and hip hop," another wrote.
A third joked: "I hope he was the support act."
Another added: "If you posted this on April Fools Day I wouldn't believe it."
"Imagine Stormzy not even being the biggest name at his own gig," wrote a fifth.
Someone else wrote: "That man exudes the most awkward version of confidence I've ever seen, he is simply unmatched."
Kathryn, who spotted Louis in the crowds, replied to a comment writing: "He was only there for the last couple of songs. No one noticed him, I was so shocked, I said hello and got a pic, he was super nice. He blends in well."
Speaking about the series, Theroux said: “I’m so excited to be embarking on this new series – something very different to the kind of TV I normally make.
"This will be a chance to meet and spend time with people I admire, getting to know them, having long form and revealing conversations, with honesty, emotion, and humour.
“To be kicking off with the genius that is Stormzy is proper pinch-me stuff. I can’t wait to get going.”
