President and owner of In-N-Out Burger, Lynsi Torres, is serving up one hefty child support payment.
According to divorce documents obtained by Radar Online, the 30-year-old fast food heiress is required to pay almost $19,000 per month in child support to her ex-husband, Richard Martinez, whom she divorced in 2011. The former couple shares joint custody of their 8-year-old twins.
In addition to the hefty monthly payment, Torres -- who was recently named the youngest female billionaire in the U.S. -- is also responsible for covering the cost of the children's private school tuition. According to the prenup, she does not owe Martinez any spousal support.
