Jennifer Lopez's past relationship with Sean "Diddy" Combs has come back to haunt her as the embattled rapper faces a slew of disturbing legal allegations, including sexual assault and sex trafficking. According to a source, the "On the Floor" singer is "horrified" by the accusations and wants no further association with her former boyfriend.

"J. Lo is horrified by all of the accusations," the insider reveraled, as reported by In Touch. "She and Diddy had talked about marriage at one point, but she left him for a reason. Now people want to know why and what she saw."

The couple dated from 1999 to 2001, and their relationship was marked by high-profile incidents, including a 1999 club shooting in which both were arrested, though charges against Lopez were later dropped, and Combs was acquitted, according to People magazine.

Now, in one of the ongoing lawsuits against Combs, a plaintiff named Rodney "Lil Rod" Jones has alleged that Combs confessed to him that he had been the shooter in the 1999 incident and that Lopez had carried the gun.

"There were many wild moments with Diddy, and it gives J. Lo the creeps to think that she was with him for so long," the source revealed, adding that the singer was "wasn't happy in the relationship."

According to the insider, Lopez stayed with Combs despite her discontent because she felt he provided her "personal security" and protection from the various death threats they both received throughout their romance.

"She doesn't want to be associated with him at all anymore," the source said, noting that the Marry Me actress has been "aware of the chaotic times she shared with the 'Last Night' vocalist" and at times seems to find herself faced with regret.

The legal troubles facing Combs, including multiple civil lawsuits accusing him of crimes ranging from drug trafficking to rape and human trafficking, have dredged up painful memories for Lopez. The insider admitted that "J. Lo has been aware of the chaotic times she shared with the 'Last Night' vocalist, and at times seems to find herself faced with regret."

"Jen's the first to admit she has made some very bad decisions," the source confessed, explaining that the mother-of-two, who shares her 16-year-old twins Max and Emme with her ex-husband Marc Anthony, "looks at her life today, with Ben, and is super grateful."

Lopez's current husband, Ben Affleck, has been a source of support and stability in her life, a stark contrast to the tumultuous relationship she shared with Combs. The insider noted that the singer "looks at her life today, with Ben, and is super grateful."

The resurfacing of these disturbing allegations against Combs has undoubtedly been a difficult and emotional experience for Lopez. As a successful and influential public figure, she has worked hard to distance herself from her past relationship and the emerging legal troubles surrounding her ex-boyfriend.

However, the unexpected mention of her name in the ongoing lawsuits against Combs has thrust her back into the spotlight, forcing her to confront the demons of her past. Despite this, Lopez appears to have found peace and contentment in her current marriage, a testament to her resilience and growth as an individual.

As the legal saga surrounding Combs continues to unfold, the spotlight will likely remain on his past relationships, including the one he shared with Jennifer Lopez. For the singer, this chapter of her life may forever cast a shadow, but her focus now appears to be on the bright future she has built with her husband, Ben Affleck.
