San Antonio Spurs star Tim Duncan may be known for his calm on-court demeanor, but the future Hall of Famer’s personal life is currently anything but settled. The 37-year-old is in the middle of a divorce battle with Amy Duncan, his wife of 12 years.

Amy Duncan initiated the divorce proceedings in March, but Tim apparently suspected his wife of misdeeds as early as last fall, the San Antonio Express-News reports. Duncan reportedly hired a private investigator to look into Amy’s behavior, prompting speculation that the Spurs star suspected his former college sweetheart was cheating. It is not yet clear if Duncan’s suspicions of infidelity are warranted.

While the Duncans’ ongoing divorce battle is sure to get messy as more details are revealed, the fractured couple will be hard-pressed to surpass the level of previous athlete divorces. Sports stars such as Tiger Woods, Chad Johnson and Tony Parker have all engaged in divorces messy enough to cause even the most jaded tabloid reporter to salivate. Take a look at six of the nastiest athlete divorce scandals of all time.

Chad Johnson

Much like his career in the NFL, Chad “Ochocinco” Johnson’s marriage to reality star Evelyn Lozada flamed out in spectacular fashion. On July 4, 2012, the former Cincinnati Bengals wide receiver married Lozada after a very public courtship, but the relationship experienced immediate problems. In August, just weeks after the wedding, Johnson was arrested for domestic battery after allegedly headbutting Lozada during a heated argument. Three days later, she filed for a divorce.

Former New York Giants great Tiki Barber’s once-sterling reputation took a big hit when details of his 2009 estrangement from wife Ginny Cha became public knowledge. In 2010, it was revealed that Barber, then 35, had left his pregnant wife to be with a 23-year-old NBC intern named Traci Lynn Johnson. Sources close to the scandal told the New York Post that Barber had lavished his younger lover with gifts and flowers and had even stayed over at her college dorm room. Then, in 2012, Barber married his one-time mistress just eight days after his divorce was finalized.

Tony Parker

Tim Duncan isn’t the only member of the Spurs to go through a messy divorce. Tony Parker’s marriage to celebrity Eva Longoria, once the toast of Hollywood, ended in utter ruin. Rumors of Parker’s infidelity began in 2007, just five months after the couple was first married, and it only got worse from there. In 2010, Longoria filed for divorce, citing “irreconcilable differences” and asking for financial compensation. During the proceedings, Extra revealed that Parker had engaged in a long-term romance with Erin Barry, the wife of fellow Spurs player Brent Barry. When news of the affair broke, along with thousands of text messages between the guilty parties, Parker's indiscretions became common knowledge.

Kris Humphries

New Jersey Nets forward Kris Humphries was just about the only person who didn’t realize that his marriage to Kim Kardashian was a bad idea. On August 20, 2011, Humphries and Kardashian were married in an E! special called “Kim Kardashian’s Fairytale Wedding.” Just 72 days later, Kardashian had filed for divorce. Humphries immediately accused the reality star of fraud, claiming that the entire relationship had merely been a publicity stunt. After over a year of back-and-forth media sniping and public insults, the ill-fated couple finally reached a divorce settlement in April 2013.

Michael Jordan

On the surface, Michael Jordan’s 2006 divorce from wife Juanita Vanoy wasn’t all that messy. The NBA legend and his longtime wife’s final divorce papers declared that the couple had settled the situation “mutually and amicably,” without any of the public disputes common in athlete divorces. However, Juanita did manage to chip away a sizable chunk of Jordan’s massive sports empire. Forbes reported that the former Mrs. Jordan had received a $168 million payout, making the couple’s separation the most costly celebrity divorce settlement in history at the time.

Tiger Woods

Tiger Woods’ divorce from Elin Nordegren will forever remain the standard by which all other athlete divorces are judged. On November 25, 2009, The National Enquirer published a story claiming that Woods had engaged in an affair with a nightclub manager named Rachel Uchitel, who turned out to be just one of Woods' many alleged sides. Over the next few months, news outlets reported on the golf legend’s alleged affairs with a slew of porn stars, waitresses and other women. Some estimates claimed that Woods had slept with as many as 120 different women. Despite the golfer’s attempts at reconciliation, Nordegren decided to go through with a divorce, which was finalized in August 2010. While reports on Woods’ exact financial losses vary, sources told TMZ that Nordegren received close to $100 million.
