Former 'NSync singer Lance Bass and his partner, Reichen Lehmkuhl, are being threatened by people angered by the "Amazing Race" contestant's book.

"We have to be very protective," Lehmkuhl told TV's "Inside Edition" Tuesday night.

"I am not going to hide," he added. "There are threats that come in from people who do not want me to be so public and expose what is going on in the military."

In the book, "Here's What We'll Say: Growing Up, Coming Out," Lehmkuhl claims he was abused for being gay in the U.S. Air Force.

Lehmkuhl told "Inside Edition" the couple hired their own security and have passed on the more severe threats to the FBI.

"Everything is being covered so we feel safe," he told the celebrity tabloid TV show.
