Selena (1997) - Responsible for skyrocketing Jennifer Lopez's acting career to what it is today, Selena proved celebrity biopics can be commercially lucrative if correctly and carefully cast. No actress would have been more ideal for fulfilling the role of the Tejano music star, and critics seemed to agree; Lopez earned a Golden Globe nomination for Best Actress in a Motion Picture.(Photo: Q Productions)

Hollywood Starlet - Lopez quit In Living Color to pursue acting in 1993 and began receiving low-profile supporting roles (Money Train, Blood and Wine, Jack).

Out of Sight - After playing a leading role in U-Turn with Sean Penn and Billy Bob Thronton, Lopez landed her biggest, most acclaimed role yet, starring opposite George Clooney in 1998’s Out of Sight — and becoming the first Latina actress to earn over $1 million for a role along the way.

Jennifer Lopez and Diddy - Their relationship fizzled out faster than the trucker hat trend, but Diddy and J.Lo were still together long enough to create a tabloid frenzy when they broke up amid rumors that Diddy was cheatin'. The rap mogul copped to his infidelities years later, admitting that he cheated on J.Lo with his baby mama, Kim Porter. He also hinted that Jenny may have gotten around the block herself, saying "Jennifer did her thing on some things, too."  (Photo: Dave Hogan/Getty Images)

Relationship With Diddy - J. Lo made headlines with her relationship with then-rising rapper-mogul Diddy. But they weren't all good: On December 27, 1999, the couple was at a Manhattan club when gunfire erupted between Combs' crew and another group. Lopez and Combs were detained by police when a gun was found in the front seat of their vehicle. Lopez wasn't charged, and Diddy narrowly avoided conviction and prison time in a high-profile trial. The pair split a year later. (Photo: Dave Hogan/Getty Images)

Marriage and Music With Marc Anthony - A new phase in Lopez's personal life once again dovetailed with transitions in her career.
