In a plot worthy of her own show, Gossip Girl star Leighton is suing her own mother, reports People. In the suit, Meester claims she was sending her mother Constance $7,500 each month to help take care of her ill younger brother, Lex. Instead of using the money to pay for medical care, Meester contends Constance spent it on plastic surgery, Botox, and other personal expenses. Upping the ante, Meester claims Constance planned to sue her for $3 million if her monthly allowance wasn’t increased to $10,000. It’s not Constance’s first run-in with the court system. In addition to a harassment lawsuit brought on earlier this year, she was convicted of smuggling marijuana from Jamaica to the U.S. in the 1980s, ultimately forcing her to give birth to Leighton from inside a halfway house.
