The Canadian singer also is contemplating legal action against the woman for defamation, his spokesman said.
Bieber, 17, spent much of last week denying the claims made by Mariah Yeater, 20, in a paternity lawsuit filed in San Diego, saying he had never met her. Yeater gave birth to a baby in July that she claimed was the result of having sex in a backstage bathroom with Bieber after a Los Angeles concert in 2010.
