It seems that much of the world is waiting to see if the five passengers on the missing Titanic Submersible will be rescued or not. 

Things look bleak, however, since TMZ reported on June 22, that oxygen in the submarine has run out.

One of the missing people is billionaire Hamish Harding, and his stepson Brian Szasz made headlines after deciding to attend a concert of rock band Blink-182 during the sea search. So, Cardi B ripped him for the move.

"Isn’t it sad you’re a whole f*cking billionaire and nobody gives a f*ck about you?” she said on social media. “Like you’re missing and motherf*ckers is ready to shake dicks at concerts. That’s crazy. I’d rather be broke and poor but knowing that I’m loved.”

Szasz was clearly offended by Cardi's message and responded.

"So you take a complete bitch like Cardi B [who] has no idea what’s going on, her career is in such turmoil that she needs clout off other people’s suffering,” he stated. “And she’s like , ‘Ah, he won’t go help, blah, blah, blah. He goes to a rock concert, this and that.’"

“[She] tries to use the situation to exploit, like the news. They’re not feeling sorry for my mom who has to take care of two kids, not really giving a f*ck that my stepdad’s probably 99 percent chance he’s dead. That doesn’t matter. Doesn’t care how we feel, just trying to f*cking make gains ... People, like, trolling, getting hate mail, all these things. It’s just f*cked up. And to have Cardi B behind it… Cardi B, f*cking grow up, get some class. You’re tasteless.”

Cardi has yet to respond to Szasz's message.
