Celebrities may have money, fame and the adoration of their fans, but sometimes that's not enough. Sometimes, they need a little extra lovin' on the side, and sometimes, they get caught.
And even though infidelity isn't exclusively committed by celebrities, cheating seems especially rampant in Hollywood.
Television personality and motorcycle customizer Jesse James was married to actress Sandra Bullock for nearly five years before allegations of his infidelity became public. To make matters worse, the scandal broke only weeks after Bullock won the Best Actress award at the 2010 Academy Awards ceremony. One of James' alleged mistresses, Michelle "Bombshell" McGee, told In Touch magazine that James led her to believe his relationship with Bullock was over. "I would never have hooked up with him if I thought he was a married man," she stated.
Ex-California governor and Hollywood action star Arnold Schwarzenegger admitted to an extramarital affair in 2011 when it was discovered that he fathered a child with one of his household employees 13 years earlier. In Schwarzenegger's 2012 memoir, titled "Total Recall: My Unbelievably True Life Story," he also admitted to an affair in 1985 with his "Red Sonja" co-star Brigitte Nielsen, though he was not yet married to Maria Shriver at the time.
Shortly after he and actress Sadie Frost divorced in 2003, Jude Law met Sienna Miller while working on the remake of "Alfie." They were engaged to be married when Law was caught cheating in 2005 with Daisy Wright, the nanny of the three children he shared with Frost. Law and Miller ended their engagement soon after, but rekindled their relationship in 2009 only to part ways again in 2011.
Los Angeles Laker Kobe Bryant was arrested on allegations of sexual assault in 2003, but he claimed that his extramarital encounter with hotel employee Katelyn Faber was consensual. After being formally charged with the crime, Bryant publicly declared his innocence and apologized for being unfaithful to his wife Vanessa, who sat by his side during the press conference. Charges were eventually dropped when Faber refused to testify against Bryant, though she also filed a civil lawsuit which has since been settled.
In November of 2009, The National Enquirer published an article accusing Tiger Woods of having an affair with Rachel Uchitel, a manager at a New York night club. Days later, Woods crashed his Escalade into a fire hydrant after speeding away from his house, and a local police chief stated that his wife, Elin Nordegren, had smashed the back windows of the vehicle with a golf club. More than a dozen of Woods' alleged mistresses would come forward in the following weeks, leading Woods to apologize for his "transgressions."
"Twilight" lovebirds Kristen Stewart and Robert Pattinson hit a bit of a snag in July of 2012 when Stewart was photographed engaging in a romantic tryst with Rupert Sanders, the married director of her film "Snow White and the Huntsman." She apologized for the affair almost immediately, and though her and Pattinson split up over the incident, rumors are currently circulating about a possible reconciliation.
LeAnn Rimes and Eddie Cibrian
Country singer LeAnn Rimes and husband Dean Sheremet separated in 2009 after it was revealed that she was having an affair with actor Eddie Cibrian, whom she met on the set of a made-for-TV movie called "Northern Lights." Cibrian was also married at the time, but divorced wife Brandi Glanville in 2010 and proposed to Rimes three months later.
Actor Hugh Grant had been in a long-term relationship with actress and model Elizabeth Hurley when he was famously arrested in 1995 for lewd conduct with prostitute Divine Brown.

Jack Nicholson and Anjelica Huston had been together for 16 years when she found out he impregnated Rebecca Broussard in 1990. In an interview with Parade magazine, Nicholson detailed the events that followed: “Anjelica's first response was, 'You have to support this woman.' Her second response was to come down to my job and beat the hell out of me. She really beat me up, I tell you. Anjelica can punch!”
Tori Spelling and Dean McDermott
Tori Spelling and Dean McDermott met and fell in love while filming a made-for-TV movie called "Mind Over Murder" in 2005 — but both were married to other people at the time. In fact, they reportedly cheated with each other the first night they met and got engaged before their divorces were finalized.
