(Cover) - EN Showbiz - Leighton Meester has won a legal battle against her mother Constance Meester.

The 26-year-old Gossip Girl star filed a lawsuit last year claiming that her mum had stolen money she had sent to take care of her younger brother.

Leighton wanted the $7,500 a month to go towards the boy's expenses because he suffers from serious medical problems.

But Constance apparently spent the cash on getting plastic surgery, Botox and hair extensions.

TMZ claims that Constance tried to convince the judge that the money was hers to do what she wanted with because her famous daughter had promised to take care of her.

But the judge ruled that no such agreement was in place.

Leighton was not suing to get any of the money back but just to have her mother leave her alone.

The actress had a troubled upbringing and was born while her mother was serving time in federal prison for her involvement in an international drugs ring. (C) Cover Media
