Hamish Harding’s stepson says he’s going through hell and worries for his stepdad

British billionaire stepson Hamish Harding has claimed he was going through hell and worried about the missing explorer – after he received backlash for attending a Blink-182 concert after the sub went missing .

Brian Szasz was hit with a massive backlash from Cardi B and others for attending a concert the day after his stepfather disappeared on the Titan submersible and asking an Only Fans model to sit on his face.

Taking to her Instagram Stories, Szasz – who claimed to only have $100 to her name – said “the whole situation is a fucking nightmare”.

“Everything about it, especially what Hamish is going through there, is just awful,” he said. ‘I haven’t slept for days, [but] it’s not about me. Obviously, [I’m] too worried about my mother [and] the situation, so I’m not budging or whatever they’re trying to accuse me of doing.

“It makes the f**king situation even worse.”

Over the past few days, Szasz has received immense criticism for attending a Blink-182 concert and commenting on an Only Fans creator’s page instead of crying.

He also claimed that the Only Fans model he asked to face sit was a friend of his and he leaves a cheeky comment “everyday” on his post and everyone “freaked out”.

“She wished me well, she wished my family well,” he said.

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

During his rampage, he also called Cardi B a complete “bitch” who was looking for “influence.”

Szasz also said he “can’t go out into the ocean” because he doesn’t have enough funds to leave California to go to Canada and has a “legal situation that keeps me here too.”

“I can’t fly, I don’t have a passport,” he admitted. He said he watched the news for two days straight and went to Blink-182’s concert for a short two-hour break to relieve himself and “just nodded”.

“The sub is stuck in this fucking Titanic, I can’t do anything about the situation at all,” he said.

Szasz first asked his followers to keep his family in mind on Wednesday morning, writing, “Please keep my family in your prayers!”

But he was soon mocked online for passing the Only Fans star.

One person said, “Lmao quote tweeting a thirst trap while your stepfather is lost at sea is crazy business.”

In a Facebook post, he first said his family “would like him to be here,” sharing a snap from the San Diego show.

Another added: “This guy loves Blink-182 and having women sitting on his face and he’s not afraid to let the world know it.”

Szasz then liked a post that read “no one can judge how you deal with this trauma,” after Cardi B made a video calling her out for attending a concert.

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

He captioned it: “It might be unpleasant to be here, but my family wants me to be at the Blink-182 show because they are my favorite band and the music helps me through difficult times!”

Cardi B called him out for not being home during this stressful time, to which he called her a “complete bitch” and said he attended the concert for a few hours of relief.

He also claimed to be friends with the Only Fan model and comments on her posts daily. Obviously, [I’m] too worried about my mother [and] the situation, so I’m not budging or whatever they’re trying to accuse me of doing. It makes the f**king situation even worse,’ he said on his Instagram Story. “Give him a break, there’s nothing wrong with that. ‘I’m just tired of the bulls**t’

Billionaire Harding, 58, and Shahzada Dawood, 48, a UK board member of the Prince’s Trust charity, along with his son Sulaiman Dawood, 19, OceanGate CEO Stockton Rush and veteran of French Navy PH Nargeolet are all aboard the submersible which disappeared on Sunday.

Oxygen on the missing Titanic submersible is expected to run out at 7 a.m. EST today, the US Coast Guard has warned – with rescue efforts to find all five people stranded on board in full force overnight.

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

The US Coast Guard led a massive international rescue effort that intensified after underwater noises were heard on Tuesday and Wednesday, although experts were unable to determine the cause of the noise.

A countdown has now begun with the vital oxygen supply set to run out at 7:08 a.m. US Eastern Time, a US Coast Guard spokeswoman said.

The wreck of the Titanic is 12,500 feet under water – about 11,000 feet deeper than many American and British submarines can dive

The announcement painted a grim picture for those trapped inside the stranded ship, but officials continued to insist the hunt is still ‘100 per cent’ a search and rescue mission.

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

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

Rescuers refuse to give up hope, U.S. Coast Guard Capt. Jamie Frederick insisted Wednesday, even as people around the world count the hours until oxygen runs out on the ship.

“We have to stay optimistic and hopeful when we’re in a search and rescue business.”
