Friends star Matt LeBlanc gave a bride and groom an extra special day when he crashed their wedding at London’s St Paul’s Cathedral while filming for the upcoming series of BBC2’s Top Gear.

LeBlanc and professional rally driver Ken Block took to London streets in a Ford Mustang as part of a tour of the capital.

The two drove past a bride, groom and wedding party as they stood on the steps of St Paul’s, with LeBlanc sticking an arm out of the car window to wave.

LeBlanc, who is apparently still unfamiliar with London, can be seen clutching a guide book in a photo taken of himself and Block in the 845bhp 4WD Hoonicorn Mustang.

The pair has also been seen driving over Tower Bridge, where they snapped a selfie using a selfie stick.
