Top Gear host Matt LeBlanc gatecrashed a wedding during the filming of the new show in London on 12 March. LeBlanc waved at the bride, bridegroom and their wedding party at St Paul's Cathedral from inside the 1965 Ford Mustang, which was being driven by professional rally driver Ken Block. The wedding party also got to witness some car stunts before the duo headed off towards Tower Bridge.

"It was very, very loud and entertaining but everyone seemed to enjoy it," onlooker Paul Bradbury, was quoted as saying by the BBC. "Matt LeBlanc walked down and had a quick look of the route before he jumped in the car," Bradbury said. "The car seemed to stall for a couple of minutes but they got going again and made a couple of takes with the wedding party on the steps," Bradbury added.

LeBlanc's tour of the capital also saw him take selfies on the Tower Bridge. LeBlanc apparently still does not know his directions around the capital well enough as he can be seen pictured clutching a tour guide in one of the photos, according to the BBC.

LeBlanc also tweeted a picture of himself from Canary Wharf saying: "Canary wharf is nice."

LeBlanc is the show's first ever non-British host in its 39-year history. The 23rd season of the show features LeBlanc along with radio DJ and presenter Chris Evans, Top Gear stalwart The Stig, Formula 1 commentator Eddie Jordan, German racing driver Sabine Schmitz, motoring journalist Chris Harris and car reviewer Rory Reid. The show will premiere in May.

Meanwhile, former host of Top Gear Jeremy Clarkson and co hosts Richard Hammond and James May are shooting for their new motoring show for Amazon. According to The Telegraph, when the trio were hosting Top Gear an estimated 350 million people tuned in to watch the show.
