Dina Shacknai Tuesday called the Zahau family's $10 million wrongful death lawsuit against her and two others in the 2011 death of Rebecca Zahau "baseless, cruel and irresponsible," Breaking Celebrity News has learned.

Dina, who is named in the lawsuit with her sister Nina Romano and former brother-in-law Adam Shacknai, said in court papers that "there is absolutely no truth to these allegations.

"Unfortunately, I have now been left with no alternative but to initiate significant measures to ensure the ongoing protection of myself, as well as my remaining family," Dina said in a statement. "The accusations are shameful and groundless and have no basis in fact or evidence."
