Alanis Morissette sued by former nanny over work conditions

Bianca Cambeiro is suing Alanis Morissette and her husband, Mario Treadway, for $30,000 in unpaid overtime and an additional $100,000 for emotional distress, claiming that the musical couple forced her to work in hostage-like conditions after Morissette gave birth to her first child, son Ever.

TMZ obtained the court documents, in which Cambeiro says she worked a 12-hour night shift for the couple three to four times a week from August 2011 to March 2013.

She alleges that Morissette and her husband was locked in Ever's bedroom for the entire shift, and wasn't allowed to leave for breaks or meals unless one of his parents was in the room.

Cambeiro's lawyer claims that the nanny, who was paid $25 an hour, was legally entitled to at least two 30-minute meal breaks per shift.

Morissette's representation has yet to comment.
