If there's one celebrity couple who does social media better than anyone else, the prize surely has to go to Blake Lively and Ryan Reynolds.

But many have forgotten that before Blake, Ryan was in a different high profile marriage...

Ryan Reynolds is one of Hollywood's best-loved actors.

He's probably best known for his role as Marvel superhero, Deadpool - in fact, he even directed the second Deadpool movie.

He's also well-known for something else.

Reynolds has one of the most beloved social media presences in the celebosphere. His Twitter is absolutely loaded with golden moments, often making fun of being a husband and a father.

Reynolds' wife is the stunning, Blake Lively.

She's had an impressive movie career, although many would argue that her most famous role is still that of the privileged socialite, Serena van der Woodsen, in teen soap, Gossip Girl.

The pair are undeniably couple goals.

Aside from being two of the most attractive people on the planet, they also seem to have an excellent sense of humor when it comes to their relationship.

Which is often depicted on social media.

Reynolds often takes to Twitter and Instagram to poke fun at married life and fatherhood.

There's one time of year in which Reynolds really shines.

Around the time of his wife's birthday, he often comes up with ingenious ways to share a sarcastic tribute to Lively - like this iconic poorly-cropped photo.

Though Lively gives as good as she gets.

On Reynolds' birthday, in response, she posted a tribute to the other famous Ryan - Ryan Gosling - cropping out her husband in the process.

Here's another classic birthday troll.

Nothing says "I love my wife," like being more focused on the celebrations of an aging country star than her own special day.

But there's one thing about Reynolds many have forgotten.

Blake Lively isn't his first famous spouse...

No, way back in 2008, he married another famous actress.

Scarlett Johansson, of course!

Scarlett Johansson is a hugely high profile star.

In fact, since 2018, she's been the world's highest-paid actress.

Her acting career has spanned decades.

And she's starred in a huge range of different genres.

There's also no doubt about it ...

She has to be one of the most beautiful women alive.

But one thing everyone always forgets?

Way back when, between 2008 and 2010, Johansson was married to Ryan Reynolds.

The reason behind the pair's split has always been hazy.

But there are some super interesting and compelling theories on the topic...

And now the internet has collectively remembered this marriage...

There have also been some theories as to why it ended.

One is that Johansson just wasn't ready to commit.

She was just 23 when the pair wed - which is a little young by anyone's standards.

"I feel I know now more of what I need in a relationship, what I want in a relationship. And I know I have more tools to communicate, not just with my partner, but with myself."

"That's not necessarily any reflection of who I was married to or what was happening in my marriage, but really where I was in my life," she explained to Glamour.

Others suggest there was a more sinister reason for the split...

"He's more traditional and she's more independent," an insider revealed to the Daily Mail.

"They're both strong-willed and stubborn people. There was a lack of warmth between them, that was troubling."

"He said it sounded like she was yelling at him every time she talked to him. When Scarlett visited Ryan on the set of The Proposal she was screaming at him in his trailer—going nuts."

Some even suggested Reynolds was jealous of Johansson's success.

"The logistics of being with another actor are challenging," she confided to E! News.

"There has to be a real understanding of how you share your time, especially when two people's careers are going at the same rate."

"Or even if one person is more successful than the other, that also proves challenging. There may be a competitive thing."

Some have even suggested Reynolds is more drawn to the limelight than Johansson.

His relationships since have been very public - but now Johansson keeps her private life private!

In fact, Reynolds has even been accused of being controlling.

"He can be an overbearing control freak. When he wanted her there, he expected her to drop everything and come to him. She got tired of the double standard," a source told the Daily Mail.

And there's an even darker rumor out there...

That the divorce happened because of infidelity.

Johansson and Reynolds divorced in 2010...

And that's the same year Reynolds started sharing red carpets with his then co-star, Lively.

There's no denying Lively entering the picture did eventually change things for the pair.
