Spike TV's official Twitter page posted the following message:

"RT @TNA_FANS: HULK HOGAN confirms "Mr. Monday Night" RVD has signed with TNA Wrestling! http://bit.ly/cZ9HmK @SPIKE_TV"

According to prowrestling.net, TNA is not pleased with this news being leaked. It's possible that Hogan did the radio interview, not realizing that the video being shot of him would end up on YouTube immediately.
