One of the more intriguing questions about tonight's Larry King 50th anniversary party in New York has already been answered. Beleaguered radio host Don Imus, a longtime friend of King's, was on the invitee list for tonight's bash, but don't expect to see him.

"He's not coming," our inside source says.

Here's who is: Fox News chief Roger Ailes, Tom Brokaw, Donald Trump, Tina Brown and Ron Howard.

Planned co-hosting duties were to be done by King's fellow CNNers Anderson Cooper, Wolf Blitzer, Soledad O'Brien and Paula Zahn, but they are all in Blacksburg covering the Virginia Tech shooting.
