re: Non-pretentious, "down to earth" Hollywood celebrities

My sister is involved with the Billboard Music Awards. At some celebrity meet and greet, my BIL ended up talking w/ Justin Timberlake over a couple of drinks. During the course of the conversation, my BIL mentions that he's planning a family vacation out west - Grand Canyon, Grand Teton, Yellowstone, Glacier, etc.
JT proceeds to act like a rep
from the western MT Chamber of Commerce. The good spots, the bad spots, the don't wanna miss spots...
By the end of the conversation, Timberlake offers to let my BIL and his 3 sons stay at his house in Western Montana for a week or so that August. My BIL suggested that, while it's an extremely generous offer, wouldn't their schedules conflict? JT assured him that he was "never there" and it would be cool.
(They didn't end up staying at his house, but I thought this was a CSB.)
