Cardi B slammed the stepson of British billionaire Hamish Harding for attending a Blink-182 concert after finding out he is aboard the missing Titanic submarine. Brian Szasz confirmed in Facebook post on Monday that he was the stepson of the explorer, before sharing a pic from the San Diego show, insisting his family would want him to be there. And in a furious social media post, Cardi B said the stepson should be “at home, crying” and waiting for updates on his stepfather's whereabouts instead of “shaking d***ks” at a concert. Cardi told her followers: “One of the billionaires, their stepson is at a concert right, at a Blink 182 concert. And people are like 'erm what is he supposed to do, be sad at the house, is he supposed to go look for him himself?' Yes!”
