Age-gap relationships. They're fascinating things.

As if celebrity relationships weren't pervy enough, trying to understand how two people make their relationships work when they're from very different times is just rather... fascinating.

And with Cher backing her relationship with her boyfriend of one year — who is 40 years her junior — it seems the love actuallyisn'tdead in Hollywood.

So we decided to take a look at the love stories of nine celebrity couples with large age gaps.

Side note: Remember when these celebs dated? Post continues below.

Cher and Alexander 'A.E.' Edwards.

Singer Cher, 77, and 37-year-old music producer Alexander Edwards briefly met during Paris Fashion Week in 2022 before reconnecting over text when a mutual friend handed him her number.

"It was really shocking, because people just don’t give out my number," she toldVanity Fair."I had been telling all my friends, 'We’re too old to go out with really younger men, and I will never fall in love on text.' So I did what I said not to do!"

What makes their relationship fascinating is their 40-year age gap – something Cher understands completely.

"No matter what happens, I love being with him," she said of Edwards. “He makes me laugh, and we have fun.

"What I learned is that it’s never too late. If you wrote out all the statistics, you would go, 'Well, this is doomed.' But we’ve been together a year, and if it was just a year, it would’ve been worth it. I’ve had the best time."

Billy Ray Cyrus and Firerose.

After a year-long engagement, singer Billy Ray Cyrus is married to Australian musician Firerose.

The pair wed earlier this month, bringing the news to Instagram.

"10/10/23 will always be the beautiful, joyous day that our two souls united as one in holy matrimony," they wrote. "It was the most perfect, ethereal celebration of love we could have ever imagined."

The couple continued, "For both of us to hear the preacher say, 'Billy Ray and Firerose Cyrus... I now pronounce you husband and wife' that was the sacred moment our new forever began. Long Live Love!"

Cyrus, 62, first connected with Firerose, 34, back when he was on the set of the Disney Channel seriesHannah Montana12 years ago.

"I loved doing that show," he remembered. "There's a couple old pine trees on the lot that look like Tennessee. [My late German Shepherd] Tex and I would go out there in the middle of the day and he'd take care of his business and we'd stretch and I'd think how much I missed Tennessee," he said, as reported by PEOPLE .

"On that given day, Firerose came out of the front door. There was almost a moment of, I don't know, recognition. I was like, 'This girl's a star.'"

They reconnected in 2021 to team up for a musical collaboration and soon fell in love.

Chris Pratt and Katherine Schwarzenegger.

After dating for about a year, Chris Pratt, 41, and Katherine Schwarzenegger, 31, got married in June 2019.

The pair officially started dating a month after Pratt divorced his ex-wife, Anna Faris, and in August 2020, they welcomed their first daughter, Lyla Maria, together.

Jay-Z and Beyonce.

Beyonce was 18 years old when she first met her future husband, Jay Z, who is 12 years her senior.

"There was no rush — no one expected me to run off and get married," Beyonce told Seventeen.

"I really don’t believe that you will love the same thing when you’re 20 as you do at 30, so that was my rule. Before the age of 25, I would never get married."

So, after eight years, the pair got married in 2008, and now share three kids together.

Sam Taylor-Johnson and Aaron Taylor-Johnson.

Sam and Aaron Taylor-Johnson first met on the set ofNowhere Boy, a film about John Lennon that Sam was directing, and Aaron was starring in.
