Video: DellaGrotte on ‘Here Comes the Boom’: ‘Don’t know how I could mess up being me’

Mark DellaGrotte’s relationship with Kevin James began in 2006 during a coaching stint on “The Ultimate Fighter 4.”

After a day on set, he and guest coach/UFC welterweight champ Georges St-Pierre went to one of James’ comedy shows on the Las Vegas strip, and he chatted backstage with the actor and comedian.

The encounter would prove fruitful.
