The youngest female billionaire in the US is only 30-years-old and she owns the burger chain In-N-Out Burger.
Lynsi Torres is the president and owner of the chain her grandfather founded back in in 1948.
Her dad took over the business but died of a drug overdose when she was just 17 and then she took it over when her mom died in 2006. She is said to be a very low-key president.
Torres has been married three times already and her current husband is a drag racer… she is a big fan of the sport and even won some races herself.
