LOS ANGELES >> Actress Debbie Reynolds, the star of the 1952 classic “Singin’ in the Rain,” died today, one day after the death of her daughter, “Star Wars” actress Carrie Fisher. Reynolds was 84.

“She’s now with Carrie and we’re all heartbroken,” said Reynolds’ son, Todd Fisher, from Cedars-Sinai Medical Center, where his mother was taken by ambulance earlier today.

He said the stress of his sister’s death “was too much” for Reynolds.

Reynolds enjoyed the very heights of show business success and endured the depths of personal tragedy and betrayal. She lost one husband to Elizabeth Taylor and two other husbands plundered her for millions. Fisher, who found lasting fame as Princess Leia in “Star Wars” and struggled for much of her life with drug addiction and mental health problems, died on Tuesday after falling ill on a plane and being hospitalized.

In her screen career, Reynolds was a superstar early in life. After two minor roles at Warner Bros. and three supporting roles at MGM, studio boss Louis B. Mayer cast her in “Singin’ in the Rain,” despite Gene Kelly’s objections. She was 19 with little dance experience, and she would be appearing with two of the screen’s greatest dancers, Donald O’Connor and Kelly, who also co-directed.

“Gene Kelly was hard on me, but I think he had to be,” Reynolds, who more than held her own in the movie, said in a 1999 Associated Press interview. “I had to learn everything in three to six months. Donald O’Connor had been dancing since he was three months old, Gene Kelly since he was 2 years old. … I think Gene knew I had to be challenged.”

“The Unsinkable Molly Brown” was based on the life of a Colorado woman who rose from poverty to riches and triumphed over tragedy, including the sinking of the Titanic.

The 1964 Meredith Willson musical, with Molly’s defiant song “I Ain’t Down Yet,” brought Reynolds her only Academy Award nomination. She also received a Tony nomination in 1973 when she starred on Broadway in the revival of “Irene,” in which her daughter also appeared.

After her transition from starlet to star, Reynolds became immensely popular with teenage girls and even more so when in 1955 she married Eddie Fisher, the pop singer whose fans were equally devoted.

The couple made a movie together, “Bundle of Joy,” which seemed to mirror the 1956 birth of Carrie. The Fishers also had a son, Todd, named for Eddie’s close friend and Taylor’s husband, showman Mike Todd.

During this period, Reynolds had a No. 1 hit on the pop charts in 1957 with “Tammy,” the Oscar-nominated song from her film “Tammy and the Bachelor.” But the Cinderella story ended after Mike Todd died in a 1958 airplane crash. Fisher consoled the widow and soon announced he was leaving his wife and two children to marry Taylor.

The celebrity world seemed to lose its mind. Taylor was assailed as a husband stealer, Fisher as a deserter of his family. Reynolds won sympathy as the innocent victim, a role emphasized when she appeared before news cameras with diaper pins on her blouse. A cover headline in Photoplay magazine in late 1958 blared: “Smiling through her tears, Debbie says: I’m still very much in love with Eddie.”

Fisher’s singing career never recovered, but Taylor, who left him for Richard Burton in 1962, remained a top star. And Reynolds’ film career flourished. She starred with Glenn Ford in “The Gazebo,” Tony Curtis in “The Rat Race,” Fred Astaire in “The Pleasure of His Company,” Andy Griffith in “The Second Time Around,” with the all-star cast in “How the West Was Won” and Ricardo Montalban in “The Singing Nun.”

She also provided the voice of Charlotte the spider in the 1973 animated “Charlotte’s Web.”

But over the years, her marital woes continued.

In 1960 Reynolds married shoe magnate Harry Karl. The marriage ended in disaster when she discovered that Karl, a compulsive gambler, had devastated her assets and left her deeply in debt. She divorced him in 1973 and toured tirelessly with her song and dance show to pay off creditors.

Reynolds’ third marriage, to Virginia businessman Richard Hamlett in 1984, proved equally disastrous. In 1992, against friends’ advice, she paid $10 million to buy and convert the faded Paddlewheel Hotel in Las Vegas into the Debbie Reynolds Hotel and Casino. She performed nightly and conducted tours of her movie memorabilia, which she had collected since MGM auctioned its artifacts in 1970.

Reynolds, who ended up filing for bankruptcy in 1997 and selling the property at auction the next year, accused Hamlett of making off with her money. She once again went on the road.

“All of my husbands have robbed me blind,” she asserted in 1999. “The only one who didn’t take money was Eddie Fisher. He just didn’t pay for the children.”

In her later years, Reynolds continued performing her show, traveling 40 weeks a year. She also appeared regularly on television, appearing as John Goodman’s mother on “Roseanne” and a mom on “Will & Grace.” Her books included the memoirs “Unsinkable” and “Make ‘Em Laugh.”

In 1996 she won critical acclaim in the title role of Albert Brooks’ movie “Mother,” in which Brooks played a struggling writer who moves back home and works on his strained relationship with Reynolds’ character. A few years earlier, she had wanted to play the mother in the film adaptation of Fisher’s bittersweet autobiographical novel “Postcards From the Edge,” which featured mother-daughter actresses. Director Mike Nichols cast Shirley MacLaine instead.

Reynolds and Fisher were featured together in the HBO documentary “Bright Lights,” scheduled for release in 2017.

Mary Frances Reynolds spent the first eight years of her life in Depression-era poverty in El Paso, Texas, where she was born on April 1, 1932. Her father, a carpenter for the Southern Pacific Railroad, was transferred to southern California and the family settled in Burbank, near Warner Bros. studio.

The girl flourished, winning 48 Girl Scout merit badges, excelling in sports and playing French horn and bass viola in the Burbank Youth Symphony. Girlfriends persuaded her to enter the beauty contest for Miss Burbank, and she won over the judges by lip-syncing to a Betty Hutton record.

She did team up with Taylor — long since divorced from Fisher — and two other veterans, Joan Collins and MacLaine, for the 2001 TV movie “These Old Broads.” The script, co-written by Reynolds’ daughter, was about aging, feuding actresses who get together for a reunion show. Reynolds would look back wryly on the Taylor affair, acknowledging that no man could have resisted her and that she actually voted for Taylor when she was up for best actress in 1960. The former romantic rivals had reconciled years before Taylor died in 2011; Reynolds recalled they had both been passengers on the Queen Elizabeth.

“I sent a note to her and she sent a note to me in passing, and then we had dinner together,” she told The Huffington Post a few months after Taylor’s death. “She was married to Richard Burton by then. I had been remarried at that point. And we just said, ‘Let’s call it a day.’ And we got smashed. And we had a great evening, and stayed friends since then.”
