Justin Bieber appears on The Late Show with David Letterman in a pre-taped interview Wednesday night, and addresses his ongoing scandal involving 20-year-old California woman Mariah Yeater, confirming he recently took a paternity test to see if he’s the father of her 4-month-old boy.

Letterman asked the pop star about the fiasco, adding it made him "see red.

"I was so angry," said Letterman, who's been targeted by stalkers and an extortionist throughout his vaunted career. "I can smell a weasel."

Bieber replied, "I could smell a weasel too, a little bit," adding he understands he's open to false accusations, and such, being a public figure "in the spotlight."

People can say whatever they want, Bieber said.

Bieber told Letterman he recently underwent a DNA test to put the issue to rest once and for all, noting the simplicity of the complicated procedure.

"They just swab your mouth," he said.
