LOS ANGELES – John Mellencamp and his wife are calling it quits.

A spokesman for the 59-year-old rocker said he and his wife of 20 years, model Elaine Irwin Mellencamp, are splitting up.

Publicist Bob Merlis declined to say Thursday if the couple had filed for divorce.

Merlis said the Mellencamps “are proud of their 20 years together and are very happy with their accomplishments both as parents and as a family.”

He said they will continue to raise their two children in Indiana.

Mellencamp’s latest album, “No Better Than This,” was released last year.

Harry Smith ends his run on CBS’ ‘Early Show’

NEW YORK – Harry Smith finished 2010 by ending his run on CBS’ “Early Show” after two stints at the morning anchor desk that totaled 17 years.

In a brief look back before his Friday signoff, Smith described his chief emotion as “one of gratitude, absolute gratitude” for his estimated 4,500 broadcasts. He also thanked his family for putting up with his demanding, wee-hours schedule.

From the archives, Smith was shown, with only slightly more hair on his head, on the 1987 premiere of “CBS This Morning.”

And in a taped tribute, Oprah Winfrey told him, “You hold the viewers, me being one of them, in the highest of esteem.”

“The Early Show” consistently trails its rivals, ratings champ “Today” on NBC and ABC’s “Good Morning America.” Last month, CBS announced a complete host turnover, replacing Smith and co-anchor Maggie Rodriguez, as well as weathercaster Dave Price.

The new team starts Monday. It consists of former Saturday “Early Show” anchors Chris Wragge and Erica Hill, as well as weathercaster Marysol Castro, formerly of the “Good Morning America” weekend edition, plus CBS News correspondent Jeff Glor as news reader.

Re-enactment of Jackson’s autopsy put off for now

LOS ANGELES – Discovery Channel International has indefinitely postponed the broadcast of a show purporting to re-enact Michael Jackson’s autopsy, the company announced Friday.

The company cited the start of hearings next week in the criminal case against Jackson’s doctor and a request by Jackson’s estate as reasons for the postponement. The decision was first reported by celebrity website TMZ.com.

John Branca and John McClain, co-executors of Jackson’s estate, accused Discovery of insensitivity toward the singer’s family in a letter Wednesday demanding that the company cancel plans for the program.

They said they were especially outraged by an Internet ad for the show, “Michael Jackson’s Autopsy,” which they described as depicting a corpse on a steel gurney covered by a sheet with a hand sticking out wearing Jackson’s signature sequined glove.

A preliminary hearing is scheduled to begin Tuesday for Jackson’s physician, Dr. Conrad Murray, who is charged with involuntary manslaughter, after which a judge will decide if there is sufficient evidence to hold Murray for trial.
