JLS hitch lift with Jenson Button
JLS hitched a lift with Formula 1 champ Jenson Button - who swapped the high-speed track for a more leisurely spin through the streets as a cabbie.
Jenson was filming a role as a black cab driver for a new TV ad for Walkers "sandwich" crisps.
The stunt took him to the Kent town of Sandwich as he chauffered the chart-topping boy band for the commercial which will air next week.
The double Brit winners admitted they were starstruck by Jenson.
JB, 23, said: "It's not every day that you meet a Formula 1 world champion. It's nice to put a face to the name - we have seen him on TV and watched Formula 1 ourselves, so to meet him was fantastic.
"He gave us a couple of signed autographs and we gave him some too, so everyone was happy."
JLS performed a mini-set of their famous hits, including chart-toppers Beat Again and Everybody In Love and new single One Shot, at Sandwich Technology school.
"It was a secret so we caused a bit of havoc and some flutter in Sandwich," JB added.
