The lawsuit filed by Hulk Hogan isn't ex-wife Linda Hogan's biggest problem after all. The crazy cougar and her boytoy are checking into Relationship Rehab to mend fences before it's too late. According to TMZ, 52-year-old Linda and her 23-year-old fiance Charlie Hill have signed on for the VH1 reality show. The odd couple have actually been an item since 2008. Hill popped the question to Hogan in 2009, although they have yet to set a date. Obviously, their stint in rehab is indicative of the fact there's something wrong in their relationship. They will also be joined by DMX and his estranged wife. One couple you won't catch in Relationship Rehab is none other than the fame-whoring duo known as Speidi. If you thought they would sell their souls to the devil for a dollar, you were wrong... well, sort of. Former Hills stars Heidi Montag and Spencer Pratt actually turned down a paid gig to appear on television. Christmas really did come early this year. A source tells TMZ that Speidi just couldn't reconcile with appearing on Relationship Rehab because they don't have any issues, a sentiment that is definitely debatable. Although they had initially entertained the option before realizing the show was about relationships, there wasn't enough money to get the couple to commit. Who knew?
