Blake Lively trolled Ryan Reynolds again by joking about cheating on him

While many celeb couples have devised special clauses in their prenuptial agreements against cheating (Justin Timberlake has to pay Jessica Beil $500,000 if he's unfaithful, while Michael Douglas would owe Catherine Zeta-Jones a whopping $5 million), it seems not all of them are that concerned about infidelity. Blake Lively and Ryan Reynolds – surprise, surprise – are one such couple, and they're even willing to joke about cheating on each other on social media.

They've been married since 2012, and as well as producing two gorgeous little children together, they've also introduced the world to the careful art of trolling your partner online. The actors are notorious for poking fun at each other on Instagram and Twitter, and you guessed it – they've done it again.

This time it was Blake who started the trolling, taking to Instagram to promote her new film, A Simple Favor. She posted a picture of two posters from the movie, one starring her and their other her co-star Anna Kendrick, and joked that she would happily cheat on her husband with Anna.

She called Anna a more attractive and "female(r)" version of Ryan, writing in the caption: "@annakendrick47 is the hotter, female(r) version of my husband... so, would it reaaaally count as cheating??"

Ooooh... burn.

Anna played along, replying cheekily: "So glad we're finally taking this public. I let Ryan take Deadpool, he can give me this."

Uhh... can you imagine? That would be a real power couple right there (sorry Ryan). Well, he seemed to think so too, adding his own comment to the thread by calling the would-be cheating scandal "the most ambitious crossover event in history". "I'll miss you both," he added. "Tell my story."

Still, you needn't worry that Blake and Ryan will really split, because they totally joke about this kind of thing all the time. On Valentine's Day, Ryan uploaded a picture of himself at the gym where it looked like he was texting on a phone.

"Why won't this damn app swipe right?!?!!" Blake commented, obviously implying that he was using Tinder. Ryan played along, replying with, "Because it's the E-harmony app." To that, Blake came back with the ultimate savagery, writing: "can you show me how to download that? Ever since Ashley Madison closed I've been so lonely."

The two sure know how to troll each other – possibly for our enjoyment but also to keep things light-hearted in their relationship. Blake has spoken before about why their marriage is so strong, especially considering the strange nature of their careers which often sees them become fake married or sexually active with other actors on screen.

"It's nice to have someone who understands what you're doing," Blake once told Good Morning America. "Especially because our job is so weird — you have to be married to other people, it's all so strange. It's never normal, even when we're both doing it. It's helpful to know when you're acting that you're in a relationship with someone else, that that's not what's actually happening."

"I have friends who aren't married to someone who's in the business, so they're like: 'oh, so you're not actually making love in that scene?' And I'm like: 'No, no, no, no, definitely not,'" she said.

Well, it seems like they totally understand each other, and they needn't worry about any cheating scandals with co-stars after all.
