It is pretty much an accepted and universal truth that Ryan Reynolds is the king of social media.
He is so quick to hit back with a well-aimed jibe or a snappy response that you'd be forgiven for thinking that he spends all of his time waiting for it, but then when would he have the time to do stuff like, you know, act in films?
Well, this time he's roped in his usual sparring partner/wife, Blake Lively, and celebrity chum Ana Kendrick and pulled them into a web of virtual #bantz.
You see, Blake went onto Instagram to show some love to her pal Anna and the new flick that sees the pair of them share the screen, which is called A Simple Favor.
She said: "[Anna Kendrick] is the hotter, female(r) version of my husband... so, would it reaaaally count as cheating??"
With this simple piece of praise, the trap was set.
Kendrick took the bait, and replied: "So glad we're finally taking this public. I let Ryan have Deadpool, he can give me this."
As ever, waiting in the wings with a quick comeback was Reynolds. He jokingly seemed to admit that he was resigned to his fate, saying: "The most ambitious crossover event in history. I'll miss you both. Tell my story."
Must be great to be a movie star with nothing better to do than create hype around you and your mate's movies on social media and watch the money come a-rolling in. Can I have a go next?
Anyway, this is just the latest episode in a long series of social media interactions between Lively and Reynolds. You have to wonder what they talk about in front of the telly of an evening.
Earlier this year Lively deleted all of her Instagram photos and unfollowed everyone, including her husband.
This led a lot of people to (wrongly) assume that the jokes had their course and Hollywood's hilarious power couple had eventually combusted.
Of course, it turned out that she then followed exclusively people called Emily as part of a promotional drive for A Simple Favor, in which her character - called Emily, would you believe - goes missing. The film is scheduled for release later this year on 14 September.
Expect the banter to accelerate... up until then, at least.
