Cruise on Letterman

From marketwatch.com:

Tom Cruise will appear as a guest on "The Late Show with David Letterman"

Tune in Tuesday, December 16 on CBS to watch Tom Cruise and David Letterman on "The Late Show with David Letterman."

PS - From this article I also read:

However, when Lauer was the guest of honor at the Friars Club annual celebrity Roast in New York City in October, Cruise arrived and joked with Lauer about the incident.

I thought it was the other way around, that it was Cruise who was fried about, but then am just a modest Belgian and don't personally follow any of these American shows.
