Enstars compiled a list of some of the most scandalous infidelities taken place in Hollywood.

Brad Pitt

Brad Pitt began his affair with Angelina Jolie on the set of their 2005 film Mr. & Mrs. Smith. Pitt was at the time married to Jennifer Aniston for five years. Pitt slammed their marriage in a 2011 interview with Parade Magazine where he said, "It became very clear to me that I was intent on trying to find a movie about an interesting life, but I wasn't living an interesting life myself. I think that my marriage [to actress Jennifer Aniston] had something to do with it." Pitt and Jolie are still together, though not married. They have six children.

Kristen Stewart

Kristen Stewart cheated on her Twilight co-star and real life boyfriend Robert Pattinson with her Snow White and the Huntsman director, Rupert Sanders, in 2012. Sanders was married to model/actress Liberty Ross at the time and together they had two kids. Pattinson forgave Stewart and they got past the heartbreak, but then ended things for good in early 2013. Ross filed for divorce following her husband's infidelity.

Coco Marrow

Coco Marrow cheated on her husband, Ice T, with a rapper name AP.9 in late 2012. She originally claimed that AP.9 was just a fan but she later admitted to the affair after the aspiring rapper posted several intimate pictures of the two together.

Eddie Cibrian and LeAnn Rimes

The stars are now married to each other but when they first got together, they were both married to other people. They began their affair after meeting on the set of their 2009 Lifetime movie Northern Lights. Cibrian at the time was married to Real Housewives of Beverly Hills star Brandi Glanville and Rimes was married to actor Dean Sheremet.

Kelsey Grammer

Kelsey cheated on wife Camille Grammer with flight attendant Katye Welsh. He admitted in September of 2012 that he should have been honest with Camille and told her he had met another woman. Camille filed for divorce in July 2010 while filming of season 1 of The Real Housewives of Beverly Hills. The divorce was finalized in February 2011. Kelsey and Kayte are now married - she became his fourth wife - and together they have a daughter.

Jennifer Lopez

While married to her second husband, dancer Criss Judd, Jennifer Lopez began sleeping with Ben Affleck while on set of their 2003 film Gigli. She eventually left Judd for good and began dating Affleck. They eventually broke up and after marrying Marc Anthony, with whom she has twins, Lopez is now dating dancer Casper Smart.

Whoopi Goldberg PLUS Jesse James

Whoopi Goldberg admitted in 2010 on The View that she cheated on her husband "five or six" times. Being somewhat sympathetic for Jesse James, who cheated on Sandra Bullock, she said, "Yes, I screwed around while I was married, yeah. I made mistakes too. It happens sometimes. Maybe he was trying to find something different too" The co-hosts were talking about James having an affair with tattoo artist Kat Von D while married to Bullock. News of James' infidelity surfaced just days after Bullock took home the Best Actress Oscar for her lead role in The Blind Side.

Tiger Woods

A number of women confessed in 2010 to having slept with famed golfer Tiger Wood while he was married to Elin Nordegren. Woods posted an apology to his website and in the statement he said, "I have let my family down and I regret those transgressions with all of my heart." The couple divorced shortly after and Woods is now dating Olympic medalist Lindsay Vonn.

Hugh Grant

In 1995, while in a relationship with British model Elizabeth Hurley, Hugh Grant was arrested off Sunset Boulevard in Los Angeles after he was caught in the act with Hollywood hooker Divine Brown. Hurley forgave him and they dated for several more years before breaking up in 2000. Hurley is currently married to Shane Warne and Grant is in a relationship with Tinglan Hong. The latter two had their second child together in 2013.
