We know Leighton Meester is suing her mom. And getting sued by her mom. Now, new reports say she wants custody of her younger brother Lex as well.
Leighton regularly sent money to her mother, Constance Meester, who served as her daughter's manager before Leighton fired her earlier this year.
The actress, 25, says this money for her brother's health needs, and that her mother used the money to get cosmetic surgeries for herself instead.
It is not known how old Lex is, or what condition(s) he suffers from. But Constance just countersued Leighton, claiming she owes her even more ... and that the 25-year-old actress came at her wielding a bottle.
Now The Roommate star just wants to make sure Lex is alright.
"Leighton is disgusted by her mother and is determined to get her brother Lex out of that situation," an insider reveals. "She wants Lex to leave their mother's California home and come to live with her in New York."
Lex, short for Alexander, recently had brain surgery, Radar reports. While Leighton has supported him willingly, she says her mom abuses this.
"[Constance] is healthy and able to work, but refuses to do so. She expects her daughter [Leighton] to support her financially," the lawsuit states.
"Leighton is really close to her brother, so she just hates that she can't be there to help him more," the source said. "She's worried for him."
Here's hoping this gets resolved ... as well as it can.
