Oprah Winfrey has spoken out after she was ambushed by a man claiming to be her 'secret son' as she left a taping of The Late Show with Stephen Colbert. The 61-year-old media mogul was photographed as she attempted to deal with the man, Calvin Mitchell, during an awkward encounter outside the Ed Sullivan Theater in New York on October 15.

The National Enquirer had arranged for Mitchell to run into Oprah after he told the tabloid he wanted to reconnect with the talk show host after becoming estranged from her for 20 years.
