The New England Patriots hosted Jon Bon Jovi at their practice field at Gillette Stadium. Bon Jovi arrived by helicopter on Tuesday and walked to the field with Patriots owner Robert Kraft.

 Bill Belichick is a huge fan of Jovi, and also a good friend.

“Jon’s a great guy. I love Jon,” Belichick told reporters in Jan. 2015. “We go back to the Giant days. That was a great time for music in New Jersey with Bruce (Springsteen) and Jon and so Jon was a big Giants fan. I had a friendship with him for several decades, followed his music career, football career. He owned the (Arena Football League’s Philadelphia) Soul, he’s been involved in that aspect of it as well. He’s been a great supporter of mine, I have a lot of fun with him.

If you’re Belichick approved you’re allowed to be at practice. If you’re not approved, you can’t even sniff the building. Just ask Brady’s Trainer Alex Guerrero.
