NEW YORK – Justin Bieber worked up his Thanksgiving appetite doing more rounds in New York, hitting “The View” and David Letterman’s show, among others, and answering some questions about that DNA test he took a week ago in New Jersey.

And, yes, that fuzz on his upper lip is in fact a moustache, on purpose.

The paternity allegation “shouldn’t even be a discussion,” he said Wednesday on “The View,” explaining that he took the test in New Jersey not because he had to but because he wanted to. Even if Mariah Yeater doesn’t submit her baby son Tristyn’s DNA for testing, he said, he “wanted everything to be out there in the open.”

(Yeater’s attorney told TMZ on Wednesday that, yes, the child will be tested. And, no, they weren’t pleased that the singer had his own test done without Team Yeater supervision.)

Whoopi Goldberg noticed Bieber’s faint moustache, but they failed to give him a chance to explain it: It’s Movember, the grow-a-‘stache-in-November campaign that each year aims to raise money and awareness for men’s health issues, including prostate cancer.

“End of November I’m gonna shave it,” he told “The View” cohosts, “… and then it’ll take another year and a half to grow back.”

Wednesday on “Late Night With David Letterman,” Bieber went into a little more detail about the DNA test, which was a mouth swab done at a lab in New Jersey with what his reps said was a clear chain of custody.

Bieber’s Thanksgiving message: “thankful for my friends, family, and fans,” he wrote on Twitter. “thankful for everyday. thank U.”

Post-surgery, actress aims to break leg

NEW YORK – Stockard Channing plans to return to a Broadway stage for the first time since undergoing arthroscopic surgery on her right knee less than a week ago.

The 67-year-old Tony Award-winning actress hoped to perform her part in “Other Desert Cities” on Friday night despite swelling and pain. Recovery periods after surgery for such injuries are usually at least two weeks.

The Jon Robin Baitz play is about a wealthy, dysfunctional family wrestling with a deep secret. It opened Nov. 3 at the Booth Theatre.

Channing’s knee collapsed after the Nov. 18 show. She missed seven performances and joked: “Blame it on the Manolos.”

Pneumonia derails tour by Michael

LONDON – George Michael has postponed all his remaining 2011 tour dates as he recovers from pneumonia, the singer’s publicist said Friday.

Michael was hospitalized in Vienna, Austria, earlier this week. A statement from publicist Connie Filippello said the 48-year-old former Wham! singer “is responding to treatment and slowly improving.”

Michael “is ill with pneumonia and any other speculation regarding his illness is unfounded and untrue,” the statement said.

Two Austrian doctors treating Michael said he had “severe community acquired pneumonia,” but “his condition has stabilized and he is responding to treatment.” They said he needed time to regain his strength.

Michael gained mega-stardom in his early 20s as half of Wham! and went on to a successful solo career. His first solo album, 1987’s “Faith,” sold 20 million copies.
