Jennifer Lynn Lopez

In March 2004, Lopez had a minor role in the film Jersey Girl, alongside Affleck. Her character, Gertrude Steiney, dies during childbirth within the first 15 minutes of the film. From the intense media scrutiny following the couple's break-up, it was noted that "they may need to put Lopez in a coffin on the poster if they want anyone to come". With a production budget of $35 million, the film was a commercial failure, earning a total of $36 million at the box office. The film, however, received generally positive reviews from critics, despite being "full of cloyingly sentimental cliches". In October, Lopez co-starred alongside Richard Gere in the drama Shall We Dance? a re-make of the 1996 Japanese film of the same title. With a production budget of $50 million, the film grossed a total of $170 million worldwide. It received generally positive reviews from critics, although it was noted that it "loses the nuances of the original", with the loss of cultural context and the addition of high-profile celebrities.
In 2004, during low-key visits to the Children's Hospital Los Angeles, which Lopez is an avid support of, she befriended eleven-year-old cancer patient Paige Patterson. Patterson attended the inaugural Noche de Niños gala for the hospital in which Lopez was presented with an award, however the morning after became even more sick and died in November 2004. Lopez has stated that Patterson made her realize why her charity work is important. Lopez dedicated Rebirth, her fourth studio album, to Patterson. According to Lopez, Rebirth "came about because I was on such a roller-coaster ride, that was my career from my first album to my last album, and I did a bunch of movie projects in between. I finally took some time just for myself, and when I came back, this was the first project I did. I felt like it was a new beginning for me, like I was, in a way, reborn. I was where I was when I made my first album". Tracy Hopkins of NBC's Today Music noted that after "fawning" over Affleck on This Is Me... Then", Lopez "wisely keeps her love life out of the spotlight" on Rebirth and only references her relationship with Anthony on a few tracks.
In May, Lopez starred alongside Jane Fonda in the romantic comedy Monster-in-Law. She received $15 million for her role as Charlie, an artist who is pitted against her fiance's mother when she does not accept her as being the right woman for her son. With a production budget of $43 million, the film grossed a total of $155 million worldwide. The film received generally negative reviews from film critics, who stated although Fonda "steals the show" in her "return to the screen", the "tired" script and "flimsy performances" make Monster-in-Law fall "flat". In August, Lopez starred alongside Robert Redford and Morgan Freeman in An Unfinished Life, a drama film based on the novel of the same name. The film was a commercial failure, only grossing $18 million worldwide with its production budget of $30 million.
