Anne Hathaway disrupted Tom Grennan’s rehearsal as he prepared to appear on The Graham Norton Show.
When the Princess Diaries actress, 40, crept up on the Not Over Yet singer, 27, he was practising backstage at the BBC studios.
The Remind Me singer is seen singing with his ensemble in a video released on Tom’s Instagram before The Witches star pops her head around the corner.
Anne appears to be enjoying the song as she mouths along to the words and bobs her head in satisfaction, much like the Kim Kardashian peeping meme.
After clapping for Tom and his colleagues, the Les Miserables actress emerges from the shadows and walks up to the All These Nights chart-topper.
While she extends her arm for a courteous handshake, the two instead embraces, with Tom keeping his calm – even if he appears shocked to find a Hollywood megastar lurking about.

Tom made an appearance on the popular chat programme, where he sang his new tune Here alongside Salma Hayek Pinault, Shania Twain, Lizzo, Julianna Moore, and Johannes Radebe.
Shania Twain discussed her open throat surgery, which left her worried she would never be able to sing again.
However, in an interview with Graham, the 57-year-old described the treatment as a “miracle” and quipped that she could now sing “extremely loudly” and “swear pretty loudly.”
She explained: ‘The operation was very invasive, and I’ve got a big scar that I am proud of.
‘I’m very happy to have a scar rather than no voice. The surgery was a miracle, and I am so grateful.
‘Going back into a studio after the operation was a discovery and I was re-learning my voice.’

Meanwhile, Julianne teased Sharper, a psychological thriller that she described as “so much joy to shoot” and “surprising.”
‘The script was wonderful, and I never knew what was coming when I read it. It stays one step ahead of you the entire time,’ she added.
The Graham Norton Show continues on Friday on BBC One at 10.40pm.
