Sergey Kosenko shared a video on Instagram of him driving through Moscow in a Bentley with his other half tied up on the roof, with the couple sharing a pair of handcuffs.
Sergey - who has five million followers - said this was one of many 'trust tests' the couple are undertaking.
Clearly, this is dangerous driving - at the very least; but remarkably, it has been reported that he was fined just 750 rubles (£7/$10).
Sergey made light of this in a sarcastic Instagram post.
He said: "I apologise. Ilona also apologises. It's a shame to lose RUB 750."
Surely though, this won't be the end of it.
In a statement, Moscow State Traffic Inspectorate said it was investigating.
It said: "Employees of the Moscow State Traffic Inspectorate initiated a check on the fact of a video posted on the Internet, in which a girl is tied on the roof of a moving car."
Indeed, lawyer Konstantin Yurkov said there could be more trouble heading his way.
He told Life: "Firstly, there may be administrative liability for violating the rules of transportation of passengers, that is, a fine of up to 1,500 rubles (£14/$20).
"But it may also be criminal - if as a result of this trip the girl was injured."
Sergey was rebuked for the stunt on social media.
One person said: "I don't see what's funny about it to be honest, and yet everyone is laughing. This is the example you set to children, most of all your own?"
Another commented: "No guys, this is not cool or fun. You set an example in any situation and the kids see it and start copying, and it may end up differently."
Last month, an influencer was caught pretending to be in business class on a flight.
Oceane El Himer tried to convince everyone online that she was travelling from Dubai to Monaco in the posh seats.
She shared an initial photograph of herself standing in front of one of the expensive seats of the aircraft. You know, the ones that turn into a bed and everything?
Then, someone - probably someone who recognised her and spotted an opportunity to bring her down a peg - shared a snap showing Oceane wearing the exact same outfit while sitting in the normal seats with everyone else.
You absolutely love to see it.
