Bret's people tell us before they separated, Bret dished out the following nugget of wisdom -- "Everyone is nervous before they hit the stage. What separates the ones who make it and [the ones that] don't is how they channel that energy."

We're not saying Bret stole that line from a fortune cookie, but he also told Lee that his lucky numbers are 4, 8, 15, 16, 23 and 42.
