The Withnail & I star was scheduled for an appearance on chat show This Morning but got stuck in gridlocked traffic in London's busy streets on the way to the appointment.

He took to Twitter.com to tells fans he was at risk of missing his slot altogether, but he eventually arrived at the ITV building on the South Bank of the River Thames just one minute before his interview began.

Grant wrote on the microblogging site, "Am due on @itv_thismorning in 15 minutes and am stuck in traffic. Expect the producer is having kittens", before later adding, "Slipped onto that @itv_thismorning sofa with a minute to spare. And it IS live. Hosts smelled delicious too. Bonus."
