Letterman to go ‘Live’

New York — David Letterman, who infrequently appears on anyone’s show but his own, will make a guest appearance next month on “Live With Regis and Kelly.”

Letterman, host of CBS’ “Late Show,” will appear Nov. 8, the syndicated morning talk show said Tuesday.

Co-host Regis Philbin and Letterman have long traded friendly barbs. He subbed for Letterman in 2000 when the late-night host underwent heart bypass surgery and again in 2003 while Letterman recuperated from an eye infection.

In anticipation of the event, “Live,” with Kelly Ripa as co-host, has released its own Top Ten list, with reasons why Letterman is appearing on the show. Among them: “Thinks Kelly is hot” and “Wants to return Regis’ copy of ‘Deuce Bigalow’ in person.”

No relapse for Mary-Kate

New York — After spending time at a treatment center for an eating disorder, Mary-Kate Olsen is under heavy scrutiny during her freshman year at New York University.

Her publicist, Michael Pagnotta, denied Tuesday a report on NBC’s “Today” show that the 18-year-old actress had suffered a setback and returned to Los Angeles.

“Somehow there’s a suggestion that she has relapsed into an eating disorder,” he said. “That’s just silly. She’s in ongoing treatment for an eating disorder with an experienced team of professionals who are available to her on both coasts. She is working very hard at being well.”

Pagnotta, in a statement, said Olsen was in Los Angeles for a few days on personal business “and will be returning to New York and to school shortly.”

Etheridge recuperating

New York — Melissa Etheridge is at home in California recovering from two operations to treat breast cancer.

Etheridge, 43, said on her Web site that a tumor and lymph nodes were removed, and that she’ll have chemotherapy next. She canceled upcoming tour dates to undergo treatment.

“I still have both of my breasts, and whether I will keep them is a bridge I have to cross later,” she said. “What an unexpected journey this is.”

The singer is still planning to shoot a pilot for ABC in which she plays a gay music teacher.

Britney ready to chill

New York — Britney Spears is taking some time away from her career to enjoy her recent marriage to dancer Kevin Federline, and she can’t wait to start a family, according to her Web site.

“My prerogative right now is to just chill and let all of the other overexposed blondes on the cover of Us Weekly be your entertainment. Good luck girls!” the Web site says.

Spears says she’s been “going & going & going” since she was 15 years old, but after she hurt her knee this summer (during a video shoot), she knew she’d have to take some time off.

She adds: “Being married is GREAT and I can’t wait to start my family!”

Her greatest hits album, “My Prerogative,” will be released on Nov. 9.
