Hulk is not only suing Gawker, he's suing them for $100 million.
Bubba the Love Sponge is also named in the lawsuit. It's all about a videotape of Hulk having sex with Bubba's ex-wife six years ago. Gawker got their hands on it somehow, and posted it. Hulk had no idea he was even being taped.
Hogan, by the way, was the best man at Bubba's wedding.
