Jennifer Lynn Lopez, nicknamed "J-Lo", is an American actress, singer, dancer, and producer. In 1991, Lopez began appearing as a Fly Girl dancer on In Living Color, where she remained a regular until she decided to pursue an acting career in 1993.

Early Movies

Lopez's first feature film was the critically acclaimed Mi Familia, or My Family, in 1995. She also appeared in Money Train (1995), opposite Wesley Snipes and Woody Harrelson, and in Jack (1996), directed by Francis Ford Coppola and starring Robin Williams.

Lopez's first big break came in 1997, when she was chosen to play the title role in Selena, a biopic of the Tejano pop singer Selena Quintillana-Perez, who was killed by a fan in 1995. Lopez earned widespread praise for her performance, including a Golden Globe nomination.

That same year, Lopez starred in the forgettable Anaconda and in Blood and Wine, opposite Jack Nicholson. Her role as federal marshal Karen Sisco in Steven Soderbergh's Out of Sight, a film based on the Elmore Leonard novel and co-starring George Clooney, further enhanced her image as a bankable movie star.

Personal Life in the Headlines

Sean "Puffy" Combs
Lopez was briefly married, in 1997, to Ojani Noa, a model and actor. She then had a lengthy and widely publicized relationship with rapper Sean "Puffy" Combs. In December 1999, Combs and Lopez were allegedly involved in a shooting incident outside a New York City nightclub, in which three people were injured. Combs was later charged with gun possession and bribery, as prosecutors claimed he offered his driver, Wardel Fenderson, $50,000 to say that the loaded gun police found at the scene of the crime was Fenderson's. Combs was acquitted of all charges, and soon confirmed that he and Lopez had separated.

Cris Judd
Shortly after that breakup was made public, Lopez began dating Cris Judd, a dancer who appeared in the video for her hit single "Love Don't Cost a Thing." After much media speculation, the couple announced their engagement in August 2001 and were married in late September. Nine months later, the couple separated.

Ben Affleck
In the fall of 2002, the star began dating actor Ben Affleck; they announced their engagement in November. Following rumors of the relationship's demise, the couple broke up in early 2004.

Marc Anthony
Lopez subsequently married singer Marc Anthony in June 2004 at a private ceremony at her Los Angeles mansion.

Returning to the big stage, Lopez found time to join forces with her husband in the 2006 biopic El Cantante. In the film, Anthony plays Hector Lavoe, the internationally acclaimed salsa singer, with Lopez alongside him as Puchi, Lavoe's wife.

In 2007, Lopez released her first Spanish language album, Como Ama una Mujer, which did well on the Latin and pop charts. She found musical success again later that same year with Brave. While the title track received some attention, Lopez's personal life generated more media interest: Once known for her revealing fashions, Lopez started wearing loose-fitting tops, creating speculation about whether she was pregnant. Many photos of her seemed to show a "baby bump," but the official announcement didn't come until November 7, 2007.

Kids
Lopez gave birth to twins February 22, 2008. The baby boy and girl, named Maximilian and Emme, were the first children for Lopez, and the fourth and fifth for Anthony.

In July 2011, Lopez and Marc Anthony announced their plans to separate. In an interview with Vanity Fair, Lopez didn't reveal the cause of the breakup, but said, "I loved myself enough to walk away." With a new hit song out, the superstar refused to be deterred. "I am positive, determined to move forward with my life, bring up my babies, and do the best job I can as a mother, entertainer and person."
