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 the whole gang 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.
Oh, well, ladies, it's coming off soon: "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 night on "Late Night With David Letterman," Bieber went into a little more detail about the DNA test, which was done at a lab in New Jersey with what his reps said was a clear chain of custody.
Letterman wanted to know, during the test, was he unconscious, and was any disrobing involved? Bieber appeared to want to know what disrobing actually was -- but, hey, cut him some slack, the kid's only 17 -- and since, as he explained, the test involves only a swab of the inside of the mouth, Dave was looking a little like a crazy old guy.
Justin's Thanksgiving message, when he finally took a break from "Under the Mistletoe" promotion? "thankful for my friends, family, and fans," he wrote on Twitter. "thankful for everyday. thank U."
