George Osborne has scolded Top Gear's Chris Evans for making a racket near Downing Street and distracting him from writing the Budget.
The Chancellor said a "noisy episode" of the BBC Two show was being filmed in central London on Sunday.
He tweeted: "Trying to write my Budget,despite noisy episode of @BBC_TopGear being filmed outside on Horseguards Parade. Keep it down please @achrisevans."
The Budget is due to be delivered on Wednesday.
On Saturday Top Gear host Matt LeBlanc and professional rally driver Ken Block surprised a bride and groom and their wedding guests at St Paul's Cathedral as they motored past, with the former Friends star sticking his arm out of the car window to wave.
Filming for the Top Gear reboot is well under way, as the new series of the BBC Two show is due to start in May.
A seven-strong line-up includes LeBlanc, radio DJ and presenter Chris Evans, and Top Gear stalwart The Stig.
Also on board are Formula 1 commentator Eddie Jordan, German racing driver Sabine Schmitz, motoring journalist Chris Harris and car reviewer Rory Reid.
