Cher Turns 70: A Look Back

The singer and actress talks about her iconic career.

One of the top-selling female recording artists in history, Cher's the only artist ever to score a No. 1 single on a Billboard chart in the sixties, seventies, eighties, nineties, 2000s and 2010s. That six-decade career means she has multiple generations of fans -- though she claims she doesn't understand why.

"What I see more than anything else is when I’m on tour, I see people carrying children on their shoulders," Cher told ABC News a few years ago. "And then, when we were in Vancouver Island, a woman on TV ... it was her 90th birthday and she [said] she wanted to spend it at my concert. And I just thought, 'You know, you go girl!'"

"I don’t really understand it," she said. "I’m thankful, I’m blessed, but I don’t really understand it at all."

Whatever the reason, Cher's grateful for the support.

"They are so loyal. I just thank God for them during all these years of having, you know, ups and downs," she added. "[W]e just have a love affair that I don’t think is ever gonna stop."

In her 70 years, Cher has proved to be the consummate entertainer, conquering the worlds of music, movies and TV, and both causing and surviving controversy. A noted philanthropist and social activist, she's also been a strong advocate for many causes, including animal rights, veterans and wounded soldiers, HIV/AIDS Prevention and -- as the mother of a transgender son, Chaz -- LGBT rights.

Earlier this year, Cher also helped donate over 180,000 bottles of water to Flint, Michigan, after its municipal water supply as found to be contaminated with lead.
