Nick Grimshaw: former BBC Radio 1 presenter mistaken on the train for Channel 4 The Piano’s judge Mika

The former BBC Radio 1 presenter, 38, who is from Oldham but now lives in north London, shared a confusing conversation that he had with a fellow train passenger with his almost 2 million Twitter followers.

He explained how the stranger asked him a question about his music skills, after mistaking him for singer-songwriter, Mika.

“A lady on the train just asked me “how’s your piano programme going luv?” After much confusion and back and forth we both realised that was a question for Mika,” Nick tweeted.

Mika, 39, is currently a judge on The Piano, Channel 4′s hunt for Britain’s most talented undiscovered pianists, which is hosted by Claudia Winkleman.

The singer-songwriter is best known for his popular hits including Love Today, Big Girl (You Are Beautiful) and Grace Kelly.

Nick added to the comedy of the situation by suggesting that he may have been crooning the lyrics from Grace Kelly whilst walking up and down the aisles.

The author of Soft Lad wrote: “To be fair to her I was singing I COULD BE BLUE I COULD BE BROWN I COULD BE ANYTHING YOU LIIIIIIKE up and down the aisles.”

Nick’s followers were quick to make comparisons between the two stars with one tweeting: “@grimmers Mika was on The One Show  a week or two back. I thought he was you until he spoke!”

Another said: “@grimmers It doesn’t surprise me, I always thought you look alike. A lot!”

Nick, who was a favourite on Radio 1 for 14 years, left the BBC show last year to explore new opportunities. He has since hosted The Great Homes Transformation for Channel 4, written a book and has also launched the Dish podcast with chef Angela Hartnett.

Grimmy, who continues to appear on Celebrity Gogglebox alongside his niece, Liv, announced his engagement to boyfriend Meshach Henry last April.

He shocked viewers of Steph’s Packed Lunch on Tuesday after stepping in to host the daytime show usually presented by Steph McGovern.

Nick said: “No, you do not have on the wrong channel, I’m keeping the studio warm for Steph.

“She has left me in charge for today.”

The decision to have Nick host the show divided opinion, however the majority of viewers welcomed him.

One tweeted: “Enjoyed watching you on Steph’s Packed Lunch today.I’m a fan now x”
