LONDON: Lisa Marie Presley has taken aim at the former nanny suing her for poor working conditions by revealing the child carer posted photos of her twin babies on social networking website Facebook.

Christine White claims she was forced to work long hours without pay, while Presley was suffering from postpartum depression - and is suing the rocker for dismissal cash.

But now Presley is countersuing her former nanny, claiming White took photographs and shot video of her twins and then posted some of them on her Facebook page, according to TMZ.com.

Presley alleges White flagrantly violated the confidentiality agreement she signed.
