11. Tito Ortiz and Jenna Jameson
If accusing one another of drug addiction and beefing on Twitter were akin to dinner dates and compliments, Tito Ortiz and Jenna Jameson would be our generation's Gone With the Wind. During their tumultuous five-year relationship, Ortiz was twice accused of domestic violence while Jameson battled a widely publicized addiction to OxyContin. The couple "officially" split in 2012 with a profound query by @titortiz: "Will life be better single? We will see." Sad. If a heavily concussed UFC fighter and retired porn star can't make it, what chance do the rest of us have?
