2:08 PM PT -- A rep for Brandy tells TMZ, "We disagree and will have further comments after we speak with our lawyers."
Brandy Norwood's former housekeeper says the singer gave her the boot because she was too old, and still owes her for work she completed ... so she's filed a lawsuit.
The housekeeper, who says she's over 60, claims she was fired by Brandy's team in February. According to the docs, obtained by TMZ, Brandy got rid of the employee because she no longer wanted an "older" housekeeper.
The housekeeper claims she wasn't paid for her last 2 days of work, and now she's suing for back pay and a whole lot more.
