Rihanna and rapper Ludacris have been added to ABC's "Dick Clark's New Year's Rockin' Eve 2007." Both acts will perform at Nokia Theatre Times Square in New York. In the meantime, Nas and Ciara are on the roster for "MTV Goes Gold: New Year's Eve 2007." The show airs live December 31 at 11 p.m. ET, with a tape delay on the West Coast. And last but not least, Ruben Studdard is playing a free New Year's Eve show in Hawaii. The Honolulu Symphony will join the "American Idol" winner for the event, dubbed Gospel Goes Classic.

Ahmet Ertegun, co-founder and longstanding chairman of Atlantic Records and the man who helped introduce the world to Ray Charles, Led Zeppelin and countless others, died Thursday (December 14) of a brain injury. He was 83.

The mogul — born into the wealthy family of a Turkish ambassador — never retired and was attending a New York concert by the Rolling Stones (one of the many bands he signed) on October 29 when he fell and incurred the injury. Perhaps fitting of the two worlds he brought together, the event was a 60th birthday party for former President Bill Clinton.

Ertegun, who survived triple-bypass surgery in 2001, later slipped into a coma and died with his family at his side.
