In a strange twist of karma, it turns out Kelis may have to be shelling out some money. According to TMZ, her housekeeper is demanding $900 in unpaid wages. All seems like a go until you find out the housekeeper is an illegal alien.

We’re told Kelis’ maid earned $150 a day for her work … and since she only worked one day a week, that means Kelis somehow fell six weeks behind on her payments.

According to sources, the housekeeper is currently exploring her legal options — trying to lock down alawyer to see if she can file anything with the California Labor Commission.
