Cardi B has hit back at the stepson of the missing British billionaire aboard the Titanic submarine, after he called her out in now-deleted tweets.

Brian Szasz was hit with backlash from the rapper and others for attending a concert the day after his stepfather went missing on the Titan submersible and asking for an OnlyFans model to sit on his face.

After Brian branded her a ‘complete b***h’ before deleting his entire Twitter account, Cardi responded by claiming he’s been ‘looking for clout,’ and branded him ‘desensitised’.

Cardi wrote: ‘The point was the whole world is praying for these people in the submarine and this man son is online shaking d***s for girls off onlyfans and going to Blink 182 concerts.

‘You was looking for clout all along, nobody knew who you were until you said that was ya stepdad!!! This is why people hate you spoiled brat billionaires yall soo desensitize.’

On Thursday, Szasz, whose stepfather is billionaire Hamish Harding, claimed to have $100 to his name and said he’s going through hell, and added the ‘whole situation is a f**king nightmare.’

‘Everything about it, especially what Hamish is going through down there is just f**king god awful,’ he said. ‘I haven’t slept in days, [but] it’s not about me.

‘Obviously, [I’m] too worried about my mom [and] the situation, so I’m not rocking out or whatever they’re trying to accuse me of doing.

‘It just makes the f**king situation that much worst.’

He also claimed the OnlyFans model he asked to sit on his face is a friend of his and he leaves a cheeky comment ‘every day’ on her post and everyone ‘flipped out.’

‘She wished me well, she wished my family well,’ he said.

‘Give it a break, there’s nothing wrong with that,’ he told his followers. ‘I’m just tired of the bulls**t.’

Szasz also said he ‘can’t go out to the ocean’ as he doesn’t have enough funds to leave California to head to Canada and has a ‘legal situation keeping me here as well.”

Rage: He faced backlash online when he asked an OnlyFans model to sit on his face after asking loved ones for ‘thoughts and prayers’ for his missing stepfather

‘I can’t get on a flight, I don’t have a passport,’ he admitted. He said he watched the news for two days straight and went to the Blink-182 concert for a quick two-hour break for relief and was just ‘nodding’ his head.

‘The submarine is stuck at the damn Titanic, there’s nothing I can do for the situation at all,’ he said.

Szasz initially asked his followers to continue to think of his family on Wednesday morning, writing, ‘Please keep my family in your prayers!’

But he was quickly mocked online for making pass at the Only Fans star.

One person said: ‘Lmao quote tweeting a thirst trap while your stepdad is lost at sea is wild business.’

Since then, Szasz appears to have deleted his Twitter account, with the page link saying ‘something went wrong, try again’.

When trying to search for his former Twitter handle, it says ‘this account doesn’t exist, try searching for another’.

In a Facebook post, he initially said that his family would ‘want him to be there,’ sharing a snap from the San Diego show.

Another added, ‘This guy loves Blink- 182 and having ladies sit on his face and he’s not afraid to let the world know.’

Szasz then went on to like a post that said ‘no one can judge the way you deal with this trauma’, after Cardi B made a video calling him out for attending a concert.

The rapper insisted the stepson should be ‘at home, crying’ and waiting for updates on his stepfather’s whereabouts instead of ‘shaking d***ks’ at a concert.

Oxygen on the missing Titanic submersible was expected to have run out as of 12pm UK time, after another huge overnight rescue effort to find the five people trapped onboard in full force overnight.

The vessel, named Titan, lost communication with tour operators on Sunday while about 435 miles south of St John’s, Newfoundland during a voyage to the Titanic shipwreck off the coast of Canada.

The US Coast Guard has been leading a massive international rescue effort which was stepped up after underwater noises were heard on Tuesday and again on Wednesday, although experts have been unable to determine the cause of the sound.

Shocking: During the last few days, Szasz has received immense criticism for attending a Blink-182 concert and commenting on the OnlyFans creator’s page instead of grieving

Officials have continued to insist that the hunt is ‘100 per cent’ still a search and rescue mission.

Rescuers including the USCG, British Navy and French and Canadian teams are picking up the pace ahead of as the window of rescue narrows.

They face a battle against time, and with less than twelve hours left of oxygen on the vessel, experts have said those inside will be trying to minimize their breathing to preserve the remaining supplies.

Rescuers are refusing to give up hope, US Coastguard Captain Jamie Frederick insisted on Wednesday, even as people around the world count down the hours until oxygen is expected to run out on the vessel.

‘We have to remain optimistic and hopeful when we are in a search and rescue case.’
