His manager James Williamson told The Sun: “Danny’s spending the night in hospital. X-rays and scans will be carried out overnight.
“He’s obviously in pain. He was running across the road and just misjudged the speed of the bus.”
An onlooker tweeted: “Every bit of the bus front window is smashed to pieces — imagine what the guy looks like.”
Danny - who was taking part in the infamous Otley Run pub crawl - has started dating 32-year-old model Kelly again after originally splitting up n 2010 after two years together.
Meanwhile, Kelly's been showing off her singing talents on video sharing site, keek.
