Jenna Jameson

Wifey of: Tito Ortiz
Tito Ortiz and Jenna Jameson have been a unit since 2006 and they've seen good and bad times together. Jenna gave birth to the couple's twins in March of 2009 but, a year later, Tito was arrested for domestic violence against the former adult starlet.

Despite the incident, the couple remains together and is one of the most well-known couples in MMA. Who said athlete x porn star relationships were all about quickies on the low? Oh yeah, we did.
