Actor/TV personality Nick Cannon supported America's inaugural Red Nose Day telethon by dancing for 24 hours straight, getting a little help from stars including Lil Kim, Stephen Merchant and Piers Morgan along the way. U.S. TV host Matt Lauer had a longer endurance challenge, as he took on a 'Tour de Red Nose' bicycle ride from Boston, Massachusetts to New York. He travelled 226 miles through four states on the five-day trek to kickstart the fundraising event, which culminated with a three-hour telethon on Thursday night (21May15).
