He's a global superstar who has sold more than 100 million records worldwide, so it's safe to say Sir Rod Stewart can afford to travel in style.
But the legendary singer, 72, shunned the luxury of a private car on Monday, instead choosing to hop on the train and tube like a regular member of the public.

Rod's wife Penny Lancaster, 45, shared photos to Instagram showing the couple "sneaking" into London for Rod's gig at the O2 Arena - and fans were both surprised and thrilled to see them embracing public transport.
The couple's journey began by train - and they posed for this fun picture at the railway station
It seems Rod wanted to go unnoticed as he wore an oversized black coat with the hood up, although the addition of sunglasses on a dreary, rainy day in the capital may have given the game away!
Rod and Penny were all smiles as they posed for a photo on the steps of a railway station platform, with Penny telling fans: "Sneaking into London by train today."
A further photo showed the famous pair had jumped on the London Underground on their arrival in the city, with Rod flashing a cheeky grin as he pulled his hood down and tried to remain incognito during a stop at Tottenham Court Road station.
"From the overground to the underground!" laughed Penny.

Fans praised the couple for their "normality", leaving hundreds of comments on the images laughing about Rod's attempt at a disguise and asking for an update as to whether he was noticed.
"Love that everyone around is oblivious they have a legend riding with them," said one Instagram user. "I'm in awe!"
A second joked of the notoriously crowded commuter trains: "Now there's someone I wouldn't mind being squashed against!"
A third pointed out there was a very modern reason why commuters may have walked past him without noticing: "Don't worry, everyone is looking down at their phone!"

Meanwhile, a fourth fan queried why Rod was standing in the photo, jokingly questioning if that meant nobody had offered the 72-year-old rockstar a seat.
"You think someone would have given the old boy a seat after all his hard graft," joked the Instagram user.
Another had words of wisdom for the star: "Next time I think it might look a tiny bit less suspicious if you dare to leave the shades in the pocket while going by the Tube!" A laughing emoji was also posted.
It was the last date on his 2016 tour

Rihanna famously got the tube to the BRITs
Rod was off to London's O2 Arena for the last date on his From Gasoline Alley To Another Country: Hits 2016 Tour. It was rearranged from November after a throat infection forced him to cancel the original date.
Rod isn't the first celebrity to choose the London Underground when it comes to making their way to the O2 Arena, situated over in Greenwich, east London.
Noel Gallagher, Jay Z, Rihanna, Chris Martin and Nicole Scherzinger have all been spied on the tube in the past, giving the commuters who noticed them a real treat in rush hour.
